某五塔单索面矮塔斜拉桥动静载荷试验研究

Research on Dynamic and Static Load Test of a Five-tower Single-plane Extradosed Cable-Stayed Bridge

文章主要根据汕头市某五塔单索面矮塔斜拉桥竣(交)工时的桥梁荷载试验检测,介绍该桥梁的结构计算、动、静力荷载试验计算模型、试验工况等内容,并通过检测主梁应变、挠度、斜拉索索力增量等内容,结合Midas Civil软件空间有限元模型的计算结果,将现场检测结果与理论计算结果进行对比分析,得出相关结论,以供参考。

Based on the bridge load test inspection at the completion(delivery)time of a five-tower single-plane extradosed cable-stayed bridge in Shantou City,this paper introduces the structural calculation,dynamic and static load test calculation models,test conditions and other contents of the bridge.By testing the strain,deflection and cable force increment of the main girder,combined with the calculation results of Midas Civil software spatial finite element model,the on-site inspection results are compared with the theoretical calculation results,and relevant conclusions are drawn for reference.
