摘要

2007年12月开工建设的泰州大桥位于江苏省中部,连接泰州与镇江,为世界首座千米级三塔连跨悬索桥,同时中塔采用世界首个纵向人字型钢塔,中塔基础采用世界上入土最深的水中沉井基础。为了建造这项宏伟的工程,针对众多技术挑战,建设者采取了一系列的创新技术:三塔悬索桥的设计技术,江中大型深井的定位着床、封底技术,人字型钢中塔的钢混结合连接技术、超厚钢板的焊接加工技术以及钢中塔异型节段的精确加工与控制技术等。

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.
