摘要
利用ANSYS有限元软件动力分析中的谱分析、模态分析功能,对拱坝进行地震动应力分析。主要是基于振型分解反应谱理论对拱坝进行抗震计算。通过此方法对沙牌拱坝进行了实例分析,最终计算结果表明沙牌拱坝满足遭遇7度地震时的抗震强度要求。
Make use of table analysis, modal analysis of ANSYS finite element software motive force to analyze shake stress analysis of the arch dam. Mainly calculate antidetonation of the arch dam is according to the shaking type table theory of decomposition reaction. This thesis carries on instance analysis by Shapai arch dam through this method, final result of calculation indicate Shapai arch dam meet experience shock strength demand at the 7 degrees of earthquakes.
