大跨度斜拉桥施工监控

桥梁监控对于整个桥梁施工来说有着举足轻重的作用,衡量一座桥梁的施工宏观质量标准就是其成桥状态的线形以及受力情况符合设计要求。就桥梁监控的任务、目标、内容以及方法进行了简单介绍,并结合西江大桥施工过程中的线形控制和索力监控等相关方面进行分析,进一步指出了监控技术已经成为桥梁施工中一个必不可少的环节。

Monitoring and Control for Large Span Cable-stayed Bridge

Monitoring and control have meant a lot to the construction of bridge. And now the standards that jud- ges the macro quality of a bridge is that the alignment and the stress condition of the finished bridge can satisfy the design requirements. This article describes the task, objective, content and method of the monitoring and control of the bridge. Also, it analyzes the control of the geometry and the cable force encountered in the construction of the Xijiang Bridge, which can further demonstrate that monitoring and control has become an important part of bridge construction.
