Analysis on the Static Load Test of a Corrugated Steel Channel Bridge in Guangdong

介绍了广东某波形钢板通道桥的静载试验,借助桥梁专用有限元计算分析软件进行仿真计算,对桥梁在试验荷载下结构实测挠度及应变与理论值进行对比分析,分析结果表明,桥梁在正常使用阶段的工作性能良好,具备一定的安全储备,并根据桥梁受力特点,提出桥梁在运营过程中应重视的几个问题。

In this paper,the static load test of a corrugated steel channel bridge in Guangdong is introduced.With the help of the bridge special finite element calculation and analysis software,the simulation calculation is carried out.The measured deflection and strain of the bridge under the test load are compared with the theoretical value.The analysis results show that the bridge has good working performance and certain safety reserve in the normal operation stage.According to the mechanical characteristics of the bridge,several problems that should be paid attention to in the operation process of the bridge are put forward.
