【Abstract】 Some problems and difficulties urgently to be solved in seismic research of high concrete arch dams were reviewed,including to find simple and practical methods for comprehensive analysis of dam foundation,dam body,and reservoir water,to work out rational safety evaluation criteria for high arch dams,to study the dynamic behavior of the strength of concrete materials,to develop the seismic input model of the dam-site river valley,and to explore aseismatic measures.Based on an analysis of some new advances in seismic research of arch dams,some suggestions were made,such as to further perfect the study of seismic response of the dam,water and foundation integrated system by means of dynamic analysis technique,to renew the idea of seismic prevention,to establish the uneven seismic model,to enhance the effectiveness research on aseismatic engineering measures,etc.更多还原
