摘　　要：庆元抽水蓄能电站下水库进水塔塔高63.00 m,抗震设防类别为甲类,设计烈度Ⅶ度,分析其地震工况下的动力响应,对结构的抗滑稳定和抗倾覆稳定有着重要意义。采用有限元分析软件ANSYS Workbench对进水塔进行三维有限元动力计算分析,根据静、动力叠加结果进行进水塔地震工况下的应力计算,并根据提取的基础面反力按照结构力学方法进行进水塔稳定性计算。计算结果表明,进水塔结构在地震工况下的应力和抗滑稳定性满足规范要求。The intake tower of the Qingyuan Pumped Storage Power Station's lower reservoir has a height of 63 meters,and is classified under seismic fortification category A with a design seismic intensity of VII.Analyzing its dynamic response under seismic conditions is crucial for ensuring the structure's stability against sliding and overturning.A three-dimensional finite element dynamic analysis is performed on the intake tower using the finite element analysis software Ansys Workbench.Based on the combined static and dynamic results,stress calculations under seismic conditions are conducted.Furthermore,stability calculations are performed using structural mechanics methods,utilizing the extracted foundation reaction forces.The results demonstrate that the stress levels and sliding stability of the intake tower structure under seismic conditions meet the required standards.
