摘　　要：以某跨越海域范围的钢便桥为例,介绍了密排横梁钢便桥方案设计、便桥荷载的选取以及荷载组合,并采用有限元软件midas Civil建立钢便桥模型,分析了钢便桥的上下部结构承载能力极限状态以及结构正常使用极限状态的受力性能。结果表明,密排横梁钢便桥方案可以满足公路施工各种荷载工况下的结构受力要求。This paper uses a steel temporary bridge spanning a sea area as an example to introduce the design scheme of a steel temporary bridge with dense cross-beam integrated bridge deck,as well as the selection of bridge loads and load combinations during the construction process.Finite element software midas Civil is employed to establish a model of the steel temporary bridge,and the ultimate limit state of the load-bearing capacity and the serviceability limit state of the structure are analyzed.The results show that the scheme of using closely spaced crossbeams for the steel temporary bridge can meet the structural load-bearing requirements under various highway construction load conditions.
