摘　　要：随着规范的修订和使用要求的提高,需要对按原有规范建造的贮液池重新进行抗震性能分析,由此验算贮液池是否满足工作性能和生产需要。本文采用两种不同的计算方法:一是拟静力的震度法,采用Midas软件建立贮液池的三维模型并考虑土的作用进行分析;二是动力时程分析方法,采用Ansys软件建立贮液池的两个典型截面的二维模型并建立土单元进行分析。通过对两种分析方法的对比,验证了震度法的可靠性,为国内地下结构抗震验算提供新的思路。With the revision of the specifications and the improvement of requirements, the seismic performance of the reservoir which was built according to the original specification need to be reanalyzed, so as to check whether the reservoir could meet the need of performance and production or not. This paper used two different methods of calculation： one is the seismic degree method of the static analysis, which is taking the soil effect into consideration to buiM a three-dimensional model of the reservoir by using the Midas software; the other is the dynamic time-history analysis method, which is using Ansys software to build a twodimensional model with two kinds of typical cross-section and establish soil unit to analysis. Through the comparison of the two analysis methods, the reliability of the seismic degree method was verified and new ideas for the seismic checking calculation of domestic underground structures were prorided.
