Question 6: What are the famous bridges in China? history? 1 China's Four Ancient Bridges

Luoyang Bridge in Quanzhou, Fujian

Luoyang Bridge, formerly known as Wan'an Bridge, is located in Luoyang, the eastern suburb of Quanzhou, Fujian Province On the river, there is the earliest existing cross-sea beam-type stone bridge in my country. Cai Xiang, the prefect of Quanzhou in the Song Dynasty, presided over the bridge construction project. It took seven years from the fourth year of Huangyou (AD 1053) to the fourth year of Jiayou (AD 1059) in the Northern Song Dynasty and cost 14 million taels of silver. This large stone bridge spans the river and the sea.

The bridge is entirely made of granite stone. When it was first built, the bridge was 360 feet long and 1.5 feet wide. There were warrior statues on both sides. The scale of the bridge construction project is huge, the craftsmanship is superb, and it is famous all over the world. Since the bridge was built more than 900 years ago, it has been repaired 17 times. The current bridge is 731.29 meters long, 4.5 meters wide and 7.3 meters high. It has 44 boat-shaped piers, 645 handrails, 104 stone lions, 1 stone pavilion and 7 stone towers. There are many inscriptions from past dynasties near the pavilion in the bridge, including "Eternal Anlan" and other Song Dynasty rock carvings; in the north of the bridge are the ruins of Zhaohui Temple and Zhenshen Temple; in the south of the bridge is Cai Xiang Temple, the famous "Wan'an Bridge" written by Cai Xiang in the Song Dynasty. The stele, erected in the temple, is known as the "three wonders" of calligraphy, writing, and sculpture. Luoyang Bridge is the beginning of the raft-shaped bridge foundation in the world and is a national key cultural relic protection unit.

Hebei Zhaozhou Bridge

Zhaozhou Bridge, also known as Anji Bridge, is located five miles south of Zhao County, Hebei Province. The rare rhyme Yupanbi is called Zhaozhou, hence the name. Zhaozhou Bridge was designed and built by Li Chun, a mason from the Sui Dynasty. It is nearly 1,400 years old and is the oldest and most majestic stone arch bridge in the world. The Zhaozhou Bridge only uses a single-hole stone arch to span it. The span of the cherry stone arch is 37.7 meters, connecting the north and south bridges (both ends of the bridge are close to the flat ground), with a total length of 50.82 meters. Taking such a huge span was an unprecedented initiative at the time. What is even more extraordinary is that two small stone arches are built on each shoulder of the large stone arch, thus changing the traditional architectural style of filling the large arch with sand and stone in the past and creating the world's first "open shoulder arch". "New bridge type. This is an amazing scientific invention. An ancient large open-shoulder stone arch bridge like Zhaozhou Bridge. Unique in the world for quite some time. In Europe, in the 14th century AD, a similar shoulder-shaped Serret Bridge appeared on the Teck River in France, more than 700 years later than the Zhaozhou Bridge, and the bridge was destroyed as early as 1809. The outstanding contribution of Li Chun, a famous stonemason in the Sui Dynasty, will shine forever in the history of bridge construction in the world.

Beijing Marco Polo Bridge

Marco Polo Bridge is located on the Yongding River in the southwest suburbs of Beijing. It is a stone bridge with two arches. The bridge was built in the 29th year of Dading in the Jin Dynasty (1189 AD) and completed in the 3rd year of Mingchang (1192 AD). It was repaired in the Yuan and Ming dynasties and rebuilt in the 37th year of Kangxi in the Qing Dynasty (1698). The bridge is 212.2 meters long and has 11 holes. The net span and sagittal height of each hole are not equal, the side holes are small and the middle hole gradually increases. The whole bridge has ten piers, with widths ranging from 5.3 meters to 7.25 meters. There are stone railings built on both sides of the bridge, and the columns are 1.40 meters high. There are stone lions carved on each column, some squatting, some lying down, some big caressing the small, some small holding the big, there are 485 in total. There are stone railings inlaid between the stone pillars, 85 cm high. There are Chinese watches, imperial stele pavilions, stele inscriptions, etc. at both ends of the bridge. There is also a square white marble stele pavilion built at both ends of the bridge. Each pavilion pillar is carved with a coiled dragon pattern. Extremely detailed. Marco Polo Bridge is world-renowned for its exquisite stone carving art. Lugou Bridge has long been famous at home and abroad. The Italian Marco Polo's book "The Travels of Marco Polo" has detailed records of this bridge. The July 7th Incident occurred here in 1937, which was the beginning of Japanese imperialism's invasion of mainland China. Therefore, Lugou Bridge became a monumental building with historical significance.

Guangji Bridge, Chaozhou, Guangdong

Guangji Bridge, also known as Xiangzi Bridge, is located in the east of Chaozhou Town, Chaoan County, Guangdong Province, spanning Han Jiang. It was first built in the sixth year of Qiandao in the Southern Song Dynasty (1170). Zeng Wang, the governor of Chaozhou, presided over the construction of the west bridge pier, which was completed in the second year of Baoqing (1226). In the first year of Shaoxing (1194), Shen Chongyu, who knew the military state affairs, took charge of the east bridge pier, and it was completed in the second year of Kaixi (1206). The whole bridge took 57 years to complete, with a total length of 515 meters. It is divided into two sections, east and west, with 18 piers. The middle section is about 100 meters wide. Due to the rapid water flow, the bridge could not be built and only boats were used to ferry it across. It was called Jeju Bridge at the time. In the 10th year of Xuande in the Ming Dynasty (1435), it was rebuilt and five piers were added, which was called Guangji Bridge. During the Zhengde period, another pier was built, totaling 24 piers. The piers are made of granite blocks, and 18 shuttle boats are used in the middle section to form a pontoon bridge, which can be opened and closed. When large ships and rafts pass by, the pontoons in the pontoon can be untied to allow ships and rafts to pass. Then return the pontoon to its original position. It is the earliest switchable large stone bridge in China and the world.

Question 7: What is the significance of the much-anticipated Hangzhou Bay Cross-sea Bridge? The Hangzhou Bay Bridge is planned by the Ministry of Transport of my country The five vertical and seven horizontal national highways, the Zhongtongjiang-Sanya Coastal Channel, is a convenient passage across the Hangzhou Bay. The completion of the bridge will become an important part of the Tongsan Line, a coastal economic artery with important strategic significance. The Hangzhou Bay Bridge conveniently connects Shanghai and Ningbo, greatly shortening the time distance between Shanghai and Ningbo and southeastern Zhejiang, forming a two-hour golden triangle between Shanghai, Hangzhou and Ningbo, and creating conditions for the establishment of a modern logistics system. The implementation of this project will promote the formation of the main framework of the transportation network in the Yangtze River Delta region and the two-vertical, two-horizontal and five-connected highway network in Zhejiang Province, strengthen the connection between Zhejiang Province’s coastal deep-water ports and Shanghai, accelerate the construction of Shanghai International Shipping Center, and promote the completion of the Shanghai International Shipping Center. As a world-class extra-large international metropolitan area centered on Shanghai, it will give full play to the economic radiation and agglomeration functions of Shanghai, relieve the bottleneck of highway traffic in Hangzhou City, Zhejiang Province, and promote the economic and social development of Ningbo City, the economic center of the southern wing of the Yangtze River Delta. It has important strategic significance. The south bank of the bridge is located in Cixi, which is of great and far-reaching significance to our city. Our city will become one of the important transportation hubs of Shanghai, Hangzhou and Ningbo from the transportation end, and further integrate into the Yangtze River Delta economic circle with Shanghai as the leader. The development space and location advantages will be greatly expanded and improved. The construction of the bridge will have an immeasurable role in accelerating the economic development of Cixi. 1. Project Overview: The Hangzhou Bay Cross-sea Bridge is a convenient passage for the main national highway, the Tongsan Line, to cross the Hangzhou Bay. The bridge starts from Zhengjiadai, Haiyan, Jiaxing City in the north, crosses the wide waters of Hangzhou Bay and ends at Cixi Waterway Bay, Ningbo City, with a total length of 36Km. After the completion of the bridge, it will shorten the land distance between Ningbo and Shanghai by more than 120 kilometers. The Hangzhou Bay Cross-sea Bridge is designed as a two-way six-lane expressway, with a design speed of 100km/h, a design service life of 100 years, and a total investment of approximately 11.8 billion yuan. The bridge has two channels, the south and the north. Among them, the north channel bridge is a diamond-shaped double-tower double-cable-plane steel box girder cable-stayed bridge with a main span of 448m, with a navigation standard of 35,000 tons; the south channel bridge is an A-type single-tower double-tower bridge with a main span of 318m. Cable surface steel box girder cable-stayed bridge, navigation standard 3000 tons. Except for the south and north channel bridges, the remaining approach bridges adopt prestressed concrete continuous box girder structures ranging from 30 to 80 meters. The Hangzhou Bay Cross-sea Bridge is currently the longest cross-sea bridge in the world that has been built or is under construction. The main project of the bridge is guaranteed to start construction smoothly in 2003, be completed in 2008, and open to traffic in 2009. A project company was established in September 2001, with an investment of 11.8 billion yuan in bridge construction and a capital of 3.85 billion yuan. Among them, Ningbo side holds 90% of the shares and Jiaxing side holds 10% of the shares. Private enterprise investment accounts for 50.25% of the company's capital. This project has requested a loan of 7 billion yuan from four banks including China Development Bank, Industrial and Commercial Bank of China, Bank of China, and Shanghai Pudong Development Bank, and a loan agreement has been signed. The economic benefits of the bridge itself are an important basis for attracting investors. According to traffic flow surveys, the number of vehicles passing through the bridge reached 52,000 in 2009, 80,000 in 2015, and 96,000 in 2027. It is estimated that the financial internal rate of return of the bridge will reach 8.03~10.1%, the investment payback period is 14.2 years, and the return on investment is 15.10% (excluding the construction period) and 12.58% (including the construction period). 2. Project characteristics: (1) The most important thing about the bridge The longest and largest amount of work is the highlight of this project. The length of the bridge is 36 kilometers, which makes it surpass the world-famous bridges such as the Chesapeake Bay Bridge in the United States and the Bahrain Causeway Bridge, and it has become the longest bridge in the world that has been built or is under construction. The longest cross-sea bridge. According to preliminary approval, the bridge requires 769,000 tons of steel, 1.291 million tons of cement, 11,600 tons of petroleum asphalt, 19,100 cubic meters of wood, 2.4 million cubic meters of concrete, and more than 7,000 pile foundations of various types. It is the largest bridge in China. The most. The 50-meter * 16-meter box girder in the South Beach is prefabricated with the entire hole, and the beam is transported on a large flatbed truck, setting a new record for heavy-duty beam transport at home and abroad. The 70-meter * 16-meter box girder of the approach bridge in Shuishui District adopts an integrated solution of whole hole manufacturing, transportation and erection. The single beam weighs 2180 tons, ranking first in the country. The diameter of the steel pipe piles driven into the Shuishui District approach bridge is 1.5-1.6 meters, the pile length is about 80 meters, and the total number exceeds 4,000. The scale of the steel pipe pile project is the largest in the history of bridge construction in the country.

Question 8: What are the types of bridges? There are four basic types of beam bridges, pontoon bridges, cable bridges and arch bridges. beam bridge. Also known as flat bridge and empty span bridge, it is a bridge with piers as horizontal distance supports, and then the beams are erected and the bridge deck is flat. This is the most commonly used type of bridge, and it appeared earlier than other bridge types in history. It comes in the form of wood, stone or a mixture of wood and stone. In the pre-Qin Dynasty, beam bridges all used wooden pillars as piers. However, this wooden pillar and wooden beam structure showed its weaknesses very early and could not adapt to the development of the situation. Therefore, they were replaced by stone pillars and wooden beam bridges, such as the multi-span long bridges built in the Qin and Han Dynasties: Wei Bridge, Ba Bridge, etc. Around the time of the Han Dynasty, pile foundation technology was invented, and stone bridge piers appeared, indicating that bridges composed of wood and stone could span wider rivers and withstand the impact of raging floods. However, because the wooden beams on the stone piers were not resistant to wind and rain erosion, bridge houses were built on the bridge to protect the bridge body. This bridge type (covered bridge) was later more common in the south, but it was first seen in the Yellow River Basin. Small and medium-sized stone beams or stone slab bridges are convenient in structure, durable in materials, and labor-saving in maintenance. They are the most popular bridge shape among the people. Especially after the Southern Song Dynasty, they became very popular in Quanzhou, Fujian, and many long stone beams were created. bridge. If a beam bridge has no piers in the middle, it is called a single-span beam bridge; if there is a pier in the water so that the bridge body forms two holes, it is called a double-span beam bridge; if there are more than two piers, it is called a multi-span beam bridge. pontoon. Also known as pontoon bridge, floating boat, or floating truss, it is also called "war bridge" because it is easy to erect and is often used for military purposes. Bridges on the water) are linked together on the water, and the boats are covered with planks for people and horses to pass. If a bridge in the strict sense is marked by a span and piers, then it is not a bridge in the full sense. Floating bridges are mainly built in places where the river surface is too wide, too deep, or where there are large fluctuations, making it difficult for ordinary wooden and stone column beam bridges to help. There are many pillars or iron cows, iron mountains, stone lions, etc. on both sides of the pontoon bridge to tie the cables. The Tianjin Bridge built on Luoshui River in Luoyang in the first year of Sui Dynasty was the first pontoon bridge to use iron chains to connect ships. Floating bridges are still commonly used in southern my country such as Jiangxi, Zhejiang, Guangxi and other places. Advantages of pontoon bridges: First, construction is fast. In the second year of Xianfeng in the Qing Dynasty (AD 1852), the Taiping Army besieged Wuchang and built two pontoon bridges across the Yangtze River in just one night. Second, the construction cost is low. Zou Shouyi of the Ming Dynasty once compared stone bridges and floating bridges in "Repairing the Fenglin Floating Bridge": "If you use a stone beam bridge, it will cost a thousand gold, but if you use a floating bridge, it will cost five hundred gold. It can be determined according to needs. "Third, it can be opened and closed at will, and it is easy to dismantle and erect. The disadvantage is that it has a small load capacity, fluctuates with the waves, and has a weak ability to withstand floods. It often needs to be dismantled in time and needs to be taken care of. The management is cumbersome. The boat, bridge deck and mooring cables need to be repaired and replaced frequently, and the maintenance cost is high. expensive. Therefore, the final destination of many floating bridges develops into wooden beam bridges, stone beam bridges or stone arch bridges. rope bridge. Also known as suspension bridge, rope bridge, suspension bridge, etc., it is a bridge suspended with bamboo ropes, rattan ropes, iron ropes, etc. as the backbone. They are mostly built on steep banks and dangerous valleys where the water flow is fast and it is difficult to build bridge piers. They are mainly found in the southwest region. The method is to build a house on both sides of the bank, with a rope-tying column and a rope-twisting column in each house, and then use a number of thick ropes to tie them flat, and then lay wooden boards across the ropes, and some also add one or two ropes on both sides. as a handrail. It first appeared in the Qin and Han Dynasties. For example, Qin Libing built a Zuo Bridge in the southwest of Yizhou (now Chengdu), Sichuan, also known as Yili Bridge, which was a bamboo cable bridge. Famous existing ones include the Luding Iron Cable Bridge and the Guanxian Bamboo Cable Bridge built in the Ming and Qing Dynasties. Crossing the cable bridge feels very thrilling, just as the ancients described crossing the cable bridge: "A person is suspended in mid-air, crossing a ravine. If he doesn't stop for a moment, he will fall into a bottomless valley." Zhimeng, a monk in the Tang Dynasty, said: "If you can't see the bottom, you will be shadowed. "In fact, it is actually safe to cross it, just as "Xu Xiake's Travels" commented on the Panjiang Bridge in Guizhou: "It looks like it is floating, but when you practice it, it remains motionless." It appeared relatively late in the history of bridges in our country, but once the arch bridge structure was adopted, it developed rapidly and became the most vital bridge type among ancient bridges. Even today, it still has broad prospects for continued development. Arch bridges can be divided into stone arches, brick arches and wooden arches. Among them, brick arch bridges are extremely rare and are only occasionally used in temples or gardens. The most common one is the stone arch bridge, which can be divided into single arch, double arch and multiple arch. The number of arches depends on the width of the river. Generally, the arch in the middle should be particularly tall, and the arches on both sides should be slightly smaller. According to the shape of the arch, it can be divided into five sides, semicircle, pointed arch, flat arch, etc. The bridge deck is usually paved with stone slabs and the bridge sides are made of stone railings.

The image of the arch bridge was first seen on the portrait bricks of the Eastern Han Dynasty. It was produced by the development of the outrigger wood and stone beam bridge and was influenced by the shapes of tomb arches, water pipes, etc. Documentary records can be found in the "Shui Jing...>>

of the Southern and Northern Dynasties.
