预应力闸墩有限元分析

根据某水电站泄洪闸孔闸墩结构及预应力锚索布置方案,应用有限元程序ANSYS建立三维有限元模型,比较预应力与非预应力情况下闸墩受力性能,验证预应力锚索布置方案的合理性,为工程设计提供参考。

According to the structure of the pier and the pre-stressed anchor layout of the spillway gate of a hydropower station,the finite element program ANSYS was used to establish a three-dimensional finite element model,compare the mechanical performance of the pier under pre-stressed and non-prestressed conditions,and verify the rationality of the pre-stressed anchor layout,so as to provide a reference for engineering design.
