明州大桥拱桥吊索索力调索分析

Analysis on Cable Adjusting of Arch Bridge Suspender Cable Force of Mingzhou Bridge

明州大桥为主跨450 m的中承式双肢拱桥,中跨主梁为漂浮式结构。以该桥为例,主要介绍大跨度钢拱桥在施工过程中吊索索力偏差的分析方式以及调索的方法,供类似工程参考。

Mingzhou Bridge is a half through double-limb arch bridge with the main span 450 m. The main beam of the middle span is the floating structure. Taking this bridge as an example, the article mainly introduces the analysis mode of suspender cable force deviation and cable adjusting method of long-span steel arch bridge in the construction process, which can be referred for the similar projects.
