摘要
天津富民桥主桥为单塔空间索面自锚式悬索桥,主缆在主跨采用三维曲线线形,吊索在横桥方向为倾斜布置。主缆初张力对该桥空间缆索体系施工方案有根本影响。重点探讨主缆初张力对该桥主索鞍与散索套安装、主缆架设、调索与体系转换等施工环节的影响问题。
The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge. The main cables of the bridge over the main span are of the three-dimensional curved geometric shape, the banger cables thereof are the inclined ones in the bridge transverse direction and the initial tensile force of the main cables has substantial influence on the construction schemes for the spatial cable system of the bridge. This paper mainly makes a study of the influence of the initial tensile force on the construction procedures of the tower saddle and splay casting installation, main cable erection, cable adjustment and system transformation of the bridge.
