摘　　要：本文对大跨度板桁斜拉桥常见的有限元建模方法及其适用性做了详细的介绍,并提出了改进的空间板梁法(M-SPB);以在建的铜陵公铁两用长江大桥为工程背景,对其进行不同深度的有限元模拟和结果分析,验证了M-SPB法的有效性。The paper introduced the finite element modeling methods and their applicabilities for large span plate and truss bridges.Moreever,modified space plate-beam model（M-SPB） was proposed.Taking the Tongling rail-road bridge as engineering background,different types of finite element models were established by the methods above and the analysis results verified the efficiency of the M-SPB method.
