摘要
泰州大桥为国内首次主跨跨径超越千米的三塔两跨悬索桥,中塔首次采用纵向人字型、横向门字型钢结构塔。文章对钢塔下塔柱大节段安装、定位、调位及设备选型、精度控制等施工技术作简单的介绍。
Taizhou Changjiang River Highway Bridge adopts a three-tower,two-span layout for the first time in the world.The longitudinal shape of the middle tower is herringbone,and the steel gallows frame is adopted in the cross direction.This paper describes the installation,locating,and adjusting construction techniques of the huge segments including the selection of hoisting equipment.
