摘　　要：基于有限元理论,利用大型分析软件ANSYS,详细叙述了仓安路斜拉桥的三维有限元动力分析模型的建立过程,讨论了翘曲刚度对自振频率的影响,对斜拉桥结构的一般动力特性进行了分析,为该桥的抗震、抗风分析提供参考。According to the theory of finite element, based on the structural analysis program - ANSYS ,3D model of Cang＇an Road Cable-stayed Bridge had been introduced in detail. Using this model, the vibrational frequency and mode had been calculated. The effect of warping constant to dynamic property had been discussed. It can be referred for aseismatic and wind-resisting analysis of this bridge.
