基于公路、铁路相关规范关于桥梁抗倾覆性能条文的不同规定，采用剪力-柔性梁格分析方法，对一座多跨独柱曲线预应力混凝土桥梁进行横向整体抗倾覆稳定性分析。采用桥梁结构专用分析程序，针对两种典型支座布置下的算例桥梁进行计算简化并建立空间网格分析模型。认为，针对公路独柱曲线窄幅桥梁，采用公、铁2种计算方法的结果基本接近。建议采用公路桥梁计算表达式进行结构设计，以增大其安全储备；采用铁路桥梁计算表达式对其进行结构验算，可有效简化验算工作，并能真实反映结构的横向整体抗倾覆性能。

Based on overturning resistance provisions of different rules of highway and railway bridge,with shear-flexible grillage analytical method,making the transverse overall anti overturning sta-bility analysis of a multi span single-pedestal curve prestressed concrete bridge.With special bridge structure analysis program,simplifying the calculation of bridge under two typical bearing arrangement and establishing the space grid analysis model.Suggesting that,for the single-pedestal curve narrow highway bridge,the results of two calculation methods is close to each other.Recommending highway bridge calculation expression for structural design so as to increase its safety reserves;using the railway bridge structure calculation for check calculation,which can effectively simplify the calculation work, and can really reflect the whole transverse overturning resistance of structure.
