6. Poems, stories, types and names about bridges ...
According to materials: wooden bridge, stone bridge, brick bridge, concrete bridge and reinforced concrete bridge; according to appearance: beam bridge, arch bridge, cable-stayed bridge and viaduct combined system bridge; according to uses: railway bridge, highway bridge, pipeline bridge and multifunctional bridge (overpass belongs to highway bridge); according to crossing objects: river-crossing bridge, valley-crossing bridge and overpass bridge across railway or highway.
The first stage is mainly in the Western Zhou Dynasty and the Spring and Autumn Period, including the previous historical era, which is the founding period of the ancient bridge. At this time, in addition to the original wooden bridge and Tingbu bridge, there are mainly two forms of bridge: beam bridge and pontoon bridge.
At that time, due to the backward level of productivity, most of them could only be built in areas with flat terrain, narrow rivers and gentle water flow, and bridges could only be wooden beams, so the technical problems were relatively easy to solve. On the other hand, pontoons are often used in rivers with wide water surface and fast flowing water.
The second stage is dominated by Qin and Han dynasties, including the Warring States and the Three Kingdoms, which is the period of creation and development of ancient bridges. The Qin and Han Dynasties were a brilliant development stage in the history of Chinese architecture. At this time, not only the bricks of artificial building materials were invented, but also the arch coupon structure with the theme of masonry structure system was created, which created the prerequisite for the emergence of arch bridges later.
The appearance of ironware in the Warring States period also promoted the multi-faceted utilization of stone materials in buildings, thus adding new components such as stone pillars, Liang Shi and stone bridge surfaces to the log beam bridge. Not only that, but also its great significance lies in the stone arch bridge came into being.
The establishment of stone arch bridge has played an epoch-making role in the history of ancient bridge construction in China, which is not only practical, but also economical and beautiful. The great development of Liang Shi stone arch bridge not only reduces the maintenance cost and prolongs the service life of the bridge, but also improves the scientific level of structural theory and construction technology.
Therefore, the use of building stone and the emergence of arch coupon technology in Qin and Han dynasties are actually a major revolution in the history of bridge construction. Therefore, according to some documents and archaeological data, about the Eastern Han Dynasty, four basic bridge types, namely, beam bridge, pontoon bridge, cable bridge and arch bridge, were formed.
The third stage is dominated by the Tang and Song Dynasties, including the Jin, Southern and Northern Dynasties and the Sui, Tang and Five Dynasties, which is the heyday of the development of the ancient bridge. Compared with Qin and Han Dynasties, Sui and Tang Dynasties had stronger national strength, and Tang and Song Dynasties achieved long-term stability and unity. The level of industry and commerce, transportation and science and technology was very developed, and it was the most advanced country in the world at that time.
After the Eastern Jin Dynasty, because a large number of Han nobles moved south, the economic center shifted from the Yellow River basin to the Yangtze River basin, which made the economy of the southeast water network area develop greatly, and the development of economy and technology in turn stimulated the development of bridges. Therefore, many bridges that attracted worldwide attention came into being at this time, such as Zhao Zhouqiao, which is an open-shouldered stone arch bridge initiated by Li Chun, a stonemason in Sui Dynasty, Hongqiao, a stoplog wooden arch bridge invented by abandoned soldiers in Northern Song Dynasty, and Wan 'an Bridge in Quanzhou, which was founded by reciting, and Xiangzi Bridge in Chaozhou, Guangdong Province, which is a combination of Liang Shi Bridge and telescopic pontoon bridge in Southern Song Dynasty.
These bridges are very famous in the history of bridges in the world, especially in Zhao Zhouqiao. Seven centuries later, similar bridges appeared in other countries in the world. Throughout the history of Chinese bridges, almost all major inventions and achievements, as well as bridges that can compete for the first place in the world, were produced at this time.
The fourth stage is Yuan Dynasty, Ming Dynasty and Qing Dynasty, which is the saturation period of bridge development, and there are almost no major innovations and technological breakthroughs. At this time, the main achievement is to repair and transform some ancient bridges, leaving many construction documents for bridge construction, providing a lot of written materials for future generations.
In addition, some arduous projects, such as Wannian Bridge in Cheng Nan, Jiangxi and Panjiang Bridge in Guizhou, were completed. At the same time, Sichuan, Yunnan and other places have built many cable bridges, and the construction technology of cable bridges has also improved.
In the late Qing Dynasty, that is, 188 1 year, with the opening of the first railway in China, another technological revolution in the history of Chinese bridges was ushered in. Bridges can be divided into wooden bridges, stone bridges, brick bridges, bamboo bridges, rattan bridges, iron bridges, salt bridges and ice bridges.
Wooden bridge is the earliest form of bridge. Almost all bridges before Qin and Han Dynasties in China were wooden bridges. Such as the earliest wooden bridge and wooden column beam bridge.
Boat bridges appeared around Shang and Zhou Dynasties, and row-column wooden beam bridges and outboard wooden beam bridges appeared around Warring States Period. However, due to the characteristics of wood itself, such as looseness, perishable, and dominated by the strength and length of materials, it is not only difficult to build bridges on rivers with wide rivers, but also difficult to build durable bridges. So in the Northern and Southern Dynasties, it was replaced by a bridge with mixed wood and stone.
Stone and brick bridges. Generally speaking, the bridge deck structure is also a bridge made of stone or brick, but bridges made of pure brick are rare, usually made of brick, wood or masonry, and stone bridges are more common.
During the Spring and Autumn Period and the Warring States Period, a wooden bridge with stone piers appeared, and the Western Han Dynasty further developed into a Liang Shi bridge with stone pillars, and a single-span stone arch bridge appeared in the Eastern Han Dynasty. In the Sui Dynasty, the world's first single-hole arc stone arch bridge with shoulder was born, while in the Tang Dynasty, Li Zhaode created a porous Liang Shi bridge. The Song Dynasty witnessed the vigorous development of large stone bridges, creating Liang Shi Bridge which spans several miles at the intersection of rivers and seas, such as Luoyang Bridge and Ping 'an Bridge in Quanzhou, and large stone arch bridges, such as Lugou Bridge in Beijing and baodai bridge in Suzhou.
Bamboo bridge and rattan bridge. Mainly distributed in the south, especially in the southwest.
Generally, it is only used on rivers with narrow river surface, or as a temporary crossing. In the early days, it was mainly a cable bridge. In the Northern and Southern Dynasties, the bamboo cable-stayed bridge was called "Ruxiang Bridge".
Later, bamboo cable bridge, bamboo pontoon bridge and bamboo slab bridge appeared. In ancient times, iron bridges included iron cable bridges and iron column bridges.
The former belongs to the category of cable bridge, which is relatively common and appeared in the Tang Dynasty. The latter is a kind of beam bridge, which is actually a wood-iron mixed bridge, which is relatively rare. Jiangxi has seen an example. Salt bridge and ice bridge.
Mainly exists in special natural environment. The former is mainly found in salt lake area of Qinghai, while the latter is mainly found in cold areas in the north.
According to the structure and appearance of bridges, there are four basic types: beam bridge, pontoon bridge, cable bridge and arch bridge. plate girder bridge
Also known as flat bridge, span beam bridge, pier horizontal support, and then set up beams.
