摘要
结合工程实例,将拟静力法中的极限平衡法和有限元强度折减法应用于地震边坡稳定性的分析,探讨了该方法的计算原理、屈服准则等.在采用极限平衡法和有限元强度折减法求得地震边坡安全系数的基础上,对边坡的安全稳定性进行了评价,同时对这两种方法所得的安全系数进行对比.计算结果表明:拟静力法应用于地震边坡稳定性分析是可行的.
Combined with practical work,the limit equilibrium method and strength reduction FEM of pseudo-static method are applied to analyzing the stability of slope under earthquake,and the calculating principle and yield criterion etc.of this method are discussed.On the basis of obtaining the safety factors of slope by using the limit equilibrium method and strength reduction FEM,the safety stability of slope is evaluated.And the safety factors obtained by the both methods are compared.The results show that the pseudo-static method is available in earthquake stability analysis of slope.
