摘　　要：采用桥梁有限元软件Midas对两座不同结构形式的"321"贝雷梁钢便桥进行建模和计算,并结合静载试验数据结果分析其受力性能.结果表明:在模拟公路-Ⅰ级设计荷载作用下,两座钢便桥承载能力均有不同程度的下降,但是下承式贝雷梁钢便桥剩余承载力大于上承式贝雷梁钢便桥,固在城市隧道建设保通工程中建议使用下承式贝雷梁钢便桥.A bridge finite element software, Midas/Civil is applied to calculate two different structural forms of the ＂321＂ Bailey beam steel temporary bridge and its mechanical behaviors are analyzed based on the data of static load test. The results show that under the design load of road level I, the carrying capacity of two temporary steel bridge declines in varying degrees, but the remaining carrying capacity of under-supporting Bailey beam temporary steel bridge is greater than that of deck type Bailey beam steel temporary bridge, so it is proposed that bottom-through Bailey beam temporary steel bridge should be used in the city tunnel construction of PAT projects.
