人行斜拉桥换索工程施工控制

摘要:

本文主要介绍人行斜拉桥的换索施工控制,通过对人行斜拉桥换索施工控制的分析,讨论在换索过程中不同施工参数在不同施工阶段下所产生的特点,借助有限元法进行理论值与实测值对比分析,得到换索后实测索力与理论索力值误差均在规范要求2%范围内,主梁线形得到较大改善,主塔偏位正常,因此换索施工过程均满足设计要求。

Abstract:

This paper mainly introduces cable replacement construction control of pedestrian cable-stayed bridge. Through the analysis of cable replacement construction control of the pedestrian cable-stayed bridge, discuss the characteristics of different construction parameters under different construction stage in the process of cable replacement, comparing the theoretical value with the measured values by finite element method, it get that error of the measured cable force and the theoretical value after cable replacement are within the scope of the specification requires 2%, main girder linear is improved, and the main tower deviation is normal, so the construction process of cable replacement can satisfy the requirements of design.
