摘　　要：基于ANSYS三维有限元分析软件,采用振型分解反应谱法对进水塔结构进行地震响应分析,分析地震作用下的塔体薄弱部位,并进行混凝土强度复核。结果表明,在地震作用下,进水塔结构位移显著增加,最大位移主要位于塔体顶部,进水塔结构拉应力有所增加,最大值主要分布在塔体腰部区域,混凝土拉应力最大值小于规范要求的抗拉强度,满足规范要求,进水塔不会产生破坏。Based on the ANSYS three-dimensional finite element analysis software,the seismic response analysis of the intake tower structure was conducted by adopting the mode decomposition response spectrum method.The weak parts of the tower body under seismic action were analyzed,and the concrete strength was rechecked.The results indicate that under seismic action,the displacement of the intake tower structure increases significantly,with the maximum displacement mainly located at the top of the tower.The tensile stress of the intake tower structure increases,and the maximum value is mainly distributed in the waist area of the tower.The maximum tensile stress of the concrete is less than the tensile strength stipulated in the specification,meeting the specification requirements,and the intake tower will not be damaged.
