摘　　要：旭龙水电站所处工程区的地震基本烈度为Ⅷ度,属于高地震区。为研究进水塔结构的抗震设计,采用三维有限元分析软件,运用振型分解反应谱法计算进水口在静动力各工况下的变形和应力分布,并对进水塔的整体稳定和基底应力进行了验算。结果表明:在各工况下,进水塔各部位一般应力均在规范许可的范围内,整体稳定及基底应力均满足规范要求,旭龙水电站进水塔结构抗震性能良好。研究成果可为类似进水塔结构设计提供参考。The basic seismic intensity of Xulong Hydropower Station isⅧdegree,which belongs to a high seismic area.In order to study the seismic design of the intake tower structure,the three-dimensional finite element analysis software was adopted,and the mode decomposition response spectrum method was used to calculate the deformation and stress distribution of the intake tower under various static and dynamic conditions,and the overall stability of the intake tower and the foundation stress were checked.The results showed that under various working conditions,the general stress in various parts of the intake tower was within the allowable range of the specifications,and the overall stability and foundation stress could meet the requirements of the specifications,the seismic performance of the intake tower structure of Xulong Hydropower Station was good.The research results can provide a reference for similar structure design of intake tower.
