摘　　要：采用通用有限元程序ANSYS建立了2种不同结构形式的索塔有限元空间实体模型,利用这2种模型分别分析了某一大跨度斜拉桥的索塔在恒载和温度荷载共同作用下的受力特征,得出承台需设置系梁的结论,并对类似结构的设计提出了若干建议。Using the general finite element program ANSYS, the finite element spatial models of 2 kinds of different structural type for the bridge tower are established. With these 2 models, stress character of tower of a long-span cable-stayed bridge are respectively analyzed on corporate operation of constant load and thermal load and conclusions of setting tie girder are obtained and some suggestions about design of similar structure are put forward.
