矶头水电站大坝的地震反应分析

Earthquake Response Analysis of the Dam in Jitou Hydroelectric Station

采用坝－水－地基系统动力耦合的边界单元法，计算在基底地震加速度情况下的矶头水电站大坝的地震反应．对坝体系统的动力特性、坝面动水压力、坝顶动力放大系数进行分析和计算，并对大坝的动力稳定性进行校核．

The earthquake response of the dam in Jitou hydroelectric station is calculated under earthquake acceleration of the foundation. It is calculated by boundary element method which is applicable to the dynamic coupling of gravity dam-water reservoir-foundation system. An analysis and a calculation are made on dynamic performance of dam body system,dynamic water pressure against dam face, and dynamic amplification of dam crest; and a check is made on dynamic stability of the dam.
