邕江大型斜拉桥变形观测方法与精度分析

Deformation Observation Method and Accuracy Analysis of Yongjiang River Large Aable-stayed Bridge

随着经济的高速发展,跨江大桥、跨海大桥越来越多,与此同时,国内外桥梁坍塌事故时有发生,因此,各省市有关部门加强了对桥梁安全性能的监测力度,2007年开始南宁市在市政府的部署下,由市政工程管理处负责,对横跨邕江上的几座大桥进行全面的健康检查,本文主要介绍白沙大桥的变形观测方法及精度分析。

With the rapid development of the economy,more and more river-crossing bridges and sea-crossing bridges were built.The relevant departments intensified the monitoring of the bridge safety in each province since the bridge collapse accident occurs sometimes all around the world.Municipal project management office began to inspect the safety of several bridges,across the Yongjiang River,under the charge of the municipal government of Nanning city since 2007.Aim at the particularity for bridge cable-stayed select method to observe the deformation of the large bridge as well as provide the methods and references for future deformation observation and safety assessment of various bridges.
