摘　　要：近年来数值方法在边坡稳定性分析中的应用得到了较快发展,特别是强度折减法引入到有限元、有限差分等数值方法之后,使其与传统的安全系数有机地联系起来,更好地为工程设计服务.建立FLAC3D三维实体模型并输入实测地震波,模拟分析填方高边坡加速度响应规律,并运用强度折减法建立动力安全系数求解方法求解其动力安全系数.The numerical method of analyzing slope stability is well-developed in the recent years, particularly, when the strength reduction method is combined with finite element method,finite difference method and other numerical method, the numerical method could relate to traditional safety coefficient, and this is better for engineering design. The paper established FLAC3D three-dimensional solid model and inputed measured seismic wave, then simulated and analyzed response pattern of acceleration. The paper also established a method to calculate dynamical safety factor base on strength reduction method.
