斜拉桥换索施工监控方法

摘要

通过分析涪陵长江大桥的工程现状，确定了该桥换索施工监控的内容，从主梁应力监控、斜拉索索力监控、主梁线形监控、主塔偏位监控四方面阐述了换索施工监控方法，并总结了一些施工技术要点，以供参考。%Through the analysis on engineering current situation of Fuling Yangtze River bridge,this paper determined the monitoring contents of cable replacement construction of the bridge,elaborated the cable replacement construction monitoring method from main girder stress monito-ring,cable-stayed cable force monitoring,main girder line monitoring,main tower bias monitoring four aspects,and summarized some construc-tion techniques,for reference.
