摘要
Abstract
In order to study the dynamic characteristics of barrier dams induced by high earthquake magnitude,shaking table test is used to simulate the dynamic characteristics of dam under the aftershock after a comprehensive investigation of the earthquake-induced characteristics of the dam.It is found that the natural vibration frequency and damping ratio of the model dam body are relatively stable.The early vibration makes the natural frequency lower,and the damping ratio tends to increase.The width of the dam is large,and the upstream and downstream slopes are gentle.The width reduces the hydraulic gradient,reducing the possibility of pipeline failure and slope instability.关键词
