Research on the Dynamic Response of Dam under Rare Earthquake through Dynamic Time-History Analysis Method

Abstract

With vigorous development of hydroelectric source in west China, the anti-seismic security issue of dam engineering attracted particular attention. This paper presented the principle of dynamic time-history analysis method and established the model with the assistance of finite element method and combined with practical engineering for further analysis on the dynamic response of displacement and stress of dam’s dynamic time-history analysis to the time history. According to the result, it is feasible and necessary to apply the dynamic time-history analysis method to study the anti-seismic performance of the dam. Furthermore, it pointed out the weak part of the dam in anti-seismic function as well as the area concentrated with critical stress, providing reference for future anti-seismic engineering and shock resistance.
