摘　　要：贝雷梁在现代桥梁建设中应用广泛,已有的研究主要聚焦于新建贝雷梁钢便桥的荷载试验,文章则以某运营贝雷梁钢便桥为例,采用Midas Civil建立结构有限元分析模型,根据分析结果进行了荷载试验方案设计,同时对现场实测结果进行了分析。静力试验结果分析表明,该钢便桥不满足汽车-15级设计荷载的使用要求;动力试验结果分析表明,该钢便桥也不宜作为人行桥使用。为保证安全,应对该桥进行封闭交通。Bailey beam is widely used in modern bridge construction.The existing research mainly focuses on the load test of the newly-built bailey beam steel temporary bridge.Taking an operating bailey beam steel temporary bridge as an example,Midas Civil is used to establish the structural finite element analysis model.According to the analysis results,the load test scheme is designed,and the field measurement results are analyzed.The static test results show that the steel temporary bridge does not meet the requirements of the automobile-15 design load.The analysis of the dynamic test results shows that the steel temporary bridge is not suitable for use as a pedestrian bridge.The bridge should be closed for traffic to ensure safety.
