Abstract
Taizhou Bridge, locating at the middle of Jiangsu Province, connecting Taizhou and Zhenjiang, started to construct in Dec. 2007. The bridge is the first kilometer level three span suspension bridge in the world. The middle tower of the bridge adopts longitudinal shape of herringbone fashion for the first time in the world. The foundation of the middle tower is the deepest caisson in the earth under water. A great many of technical innovations are carried out to construct the great engineering project, such as the design techniques of the three-tower suspension bridge, the precise locating and bottom-sealing technique of the super scale caisson foundation, the manufacture, connection techniques of steel and concrete in the middle tower, the welding of extra thick steel plate and manufacturing and control of abnormal sections of the middle tower.
