摘　　要：瀑布沟尾水隧洞出口高边坡稳定性问题突出。本文采用动力有限元分析方法,研究地震荷载作用下边坡的动力响应特性,揭示边坡在地震作用下的变形、速度、加速度与应力分布特性,以及对边坡稳定性的影响。The problem of high slope stability is outstanding. The paper studies dynamic response characteristic of slope under earthquake load with dynamic fin ite element method, reveals deformation, velocity, acceleration and stress distr ibution of slope under earthquake load and influence to slope stability.
