摘　　要：分别利用桥梁博士、Midas和ANSYS软件建立了某变截面异形连续梁桥的单梁模型、梁格模型和三维实体模型,通过静力分析对比,结果表明:不同模型都可以准确表达桥梁的纵向受力特性,实际工程中可根据研究重点的侧重选用不同模型。The plane frame model, beam grid model and 3 D solid model of a variable cross-section continuous beam bridge were established using Dr. bridge, Midas and ANSYS. Static analysis results show that three kinds of models can accurately express the longitudinal characteristics of the bridge. Different models can be chosen according to the research emphasis in practical engineering.
