大表孔拱坝应力分析

Stress Analysis of Arch Dam with Large Upper Orifices

结合工程实例介绍用有限元软件(ANSYS)计算坝顶设有大表孔的拱坝应力的过程,所得计算结果反映了坝顶设有大表孔的拱坝的实际应力分布情况。用有限元法(ANSYS)进行大表孔拱坝应力计算可大大提高计算精度和工作效率,为设计提供便利,计算成果可靠合理,具有较大的实用价值。

Combining with an engineering example, the writer introduces stress analysis process of an arch dam with large upper orifices using finite element program（ ANSYS）. The results could reflect actual status of stress distribution for the dam. Analysis on stress of similar arch dam using finite element method （ANSYS） could improve calculating speed and accuracy, therefore, have larger practice value.
