Luoyang Bridge, the earliest existing cross-sea beam-type stone bridge in my country, is located on the Luoyang River in the eastern suburbs of Quanzhou City, Fujian Province. It is the beginning of the raft foundation of bridges in the world. , is a national key cultural relic protection unit.
Luoyang Bridge, formerly known as "Wan'an Bridge". Cai Xiang, the prefect of Quanzhou in the Northern Song Dynasty, presided over the bridge construction project. From the fifth year of Huangyou (1053 AD) to the fourth year of Jiayou (1059 AD), it took seven years and fourteen million taels of silver to build this large stone bridge across the river and the sea. According to historical records, when it was first built, the bridge was 360 feet long and 360 feet wide. One foot and five feet, warrior statues stand on both sides. The scale of the bridge construction project is huge, and the structural technology is superb. It is famous all over the world. [Picture of Luoyang Bridge]
Since the bridge was built more than 900 years ago, it has been repaired seventeen times. .The major repairs were carried out in the eighth year of Shaoxing in the Song Dynasty (1138 AD), and the bridge was damaged by hurricanes. Shao Shou Zhao Sicheng repaired it; during the Xuande period of the Ming Dynasty (1426-1435), the bridge site sank, and the tide came, and the bridge was destroyed. The prefect Feng Zhen ordered the county Li Junyu (also known as Li Wu) increased Zhengchun's height by three feet; in the 32nd year of Wanli (1597 AD), there was a major earthquake, the bridge collapsed, and the foundation sank, so the prefect Jiang Zhili repaired it; in the 8th year of Yongzheng's reign in the Qing Dynasty (1730 AD) In autumn, the bridge collapsed and was repaired by the county magistrate Gong Zhiqi. In the 20th year of the Republic of China (1932 AD), Commander Cai Tingkai rebuilt it into a reinforced concrete highway bridge, with the bridge deck increased by 2 meters. It was severely damaged during the Anti-Japanese War; March 1993-1996 In October, the state allocated more than 6 million yuan in special funds to implement the Luoyang Bridge protection and restoration project. The current bridge is 742.29 meters long, 4.5 meters wide, and 7.3 meters high. It has 44 boat-shaped piers, 645 handrails, 104 stone lions, and There are stone pavilions and 7 stone pagodas.
There are numerous inscriptions from past dynasties near the pavilion in the middle of the bridge, including "Eternal Anlan" and other Song Dynasty mosaic rock inscriptions; in the north of the bridge are the ruins of Zhaohui Temple and Zhenshen Temple; in the south of the bridge is Cai Cai Xiang Temple, the famous Song Dynasty stele of Cai Xiang's "Wan'an Bridge" is erected in the temple, which is known as the "three wonders" of calligraphy, writing, and sculpture.
The construction of Luoyang Bridge is a symbol of A major contribution to the world's bridge science. Due to the strong tide of the Luoyang River at that time, the "water was five miles wide" and "inaccessible", the base of the bridge was destroyed. The bridge builders created a new type of bridge that was not recognized until modern times. The bridge foundation - a raft-shaped foundation, is to throw human-sized stones along the central axis of the bridge to form a short stone embankment connecting the bottom of the river, and then build boat-shaped piers on it. At the same time, "surging waves raise the boat and float the frame" They used the wonderful method of "beam" to put large stone slabs weighing several tons on the bridge deck. They also cultivated a large number of oysters under the bridge and glued the bridge foundation stones and pier stones into a solid whole. This is the most ingenious thing in the history of bridge building. The "Oyster Planting and Foundation Consolidation Method" is also the first pioneering work in the world to apply biology to bridge engineering. The completion of Luoyang Bridge not only turned the Luoyang River natural moat into a thoroughfare, but also played an important role in the development of Quanzhou's overseas transportation industry.
