铁路矮塔斜拉桥索塔锚固区局部应力分析

摘要

An extra-dosed cable-stayed bridge is taking as the practical engineering background to make the finite element analysis of the main tower by large software Ansys. The size and distribution of the concrete stress of the anchorage zones in 3 200 kN design loads are obtained, which verifies the security of the pylon design,enriches spatial stress analysis of the anchorage zone of extra-dosed cable-stayed bridge and plays a positive role in the design and construction of the project.%以某矮塔斜拉桥为实际工程背景,采用Ansys大型软件对其主塔进行了有限元分析.得出了在3200kN的设计荷栽作用下,其锚固区混凝土应力的大小及分布情况,验证了索塔设计的安全性,丰富了矮塔斜拉桥索塔锚固区的空间应力分析,对工程的设计与施工起到了积极作用.
