【Abstract】 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.更多还原
