摘　　要：采用软件建立某混凝土拱坝三维有限元模型,分析了该混凝土拱坝在空库、满库下的自振特性,采用振型分解反应谱法对拱坝在地震工况下的响应进行了计算。计算结果表明,拱坝设计方案坝体位移不大,应力分布合理,为工程设计提供了可靠依据。Software was used to build a three-dimensional finite element model of an arch dam, and the vibration characteristics of the concrete arch dam in both empty and full reservoirs were analyzed. The calculation of the dam＇s response in seismic condition adopted modal analysis response spectrum method. The result showed that the displacement of the dam＇s design was small, and the distribution of stress was rational. The method provided a reliable base for engineering design.
