基于ANSYS的石膏山拱坝三维弹塑性分析

Three Dimensional Elasto-plastic Analysis Based on ANSYS for Shigaoshan Reservoir's Arch Dam

利用大型商用软件ANSYS对石膏山水库单曲拱坝进行了三维弹塑性分析,阐述包括工程地形、坝体温度的整个拱坝的建模方法过程,根据弹塑性分析成果复核了原设计中的多拱梁分载法,对工程设计和施工提供了重要参考和指导。

Shigaoshan Reservoir＇s arch dam was taken three dimensional elasto-plastic analysis by using ANSYS which is a large commercial software. This article introduces the entire modeling method for arch dam which includ- ing the terrain and dam body temperature. According to the results of elasto-plastic analysis ,it checks for the multi- pie arch-cantilever safety method of the original design, which provides important reference and guidance on the de- sign and construction.
