摘　　要：利用ANSYS程序的三维实体单元和子模型技术 ,对某立交桥V形支撑局部结构模型进行了应力分析 ,绘出了各部位等应力迹线 ,并揭示了常规内力分析中所不能发现的一些问题 。By using the Solid element of ANSYS program, a stress analysis for a model of the partial structure of V support of a cloverleaf junction was conducted. The iso-stress traces of the various parts of the model were plotted, and some problems that cannot be found in the routine analysis for internal forces are revealed, which provides a reliable basis for rationally determining types and design of the partial structures of the V support.

关 键 词：V形支撑 空间有限元分析 等应力迹线 局部结构模型 应力分析 结构设计 立交桥
