摘　　要：以在建某斜拉桥为工程背景,采用大型有限元计算软件ANSYS建立主塔节段三维有限元实体模型,对主塔下塔柱预应力布置及其对应的应力分布等关键因素进行了计算分析研究,分析总结了宝石形主塔下塔柱受力情况,研究结果对类似结构形式的主塔结构设计提供参考。Based on a under-construction cable-stayed bridge project as background, a 3D finite element modle of the main tower was built with ANSYS software. The layout of prestressing tendons in the transverse beam,force transmission path and stress distribution in the tower were analyzed and discussed, which can be a reference to future design of similar structures.
