基于强度折减的二维边坡稳定性方法研究

摘要

结合工程实例,采用有限元强度折减法对高陡边坡进行了静力及地震条件下的稳定性分析,探讨了该方法的计算原理、屈服准则,在求得地震边坡安全折减系数的基础上,对边坡的安全稳定性进行了评价,同时对这两种条件下所得的安全折减系数进行对比,计算结果表明,有限元强度折减法对于边坡稳定性分析是可行的。%Combined with the engineering example,the high steep slope stability is analysed under static and the earthquake conditions by the finite element strength reduction method and the method of calculating principle and yield criterion is discussed.The stability of slope is evaluated and the safety coefficient of the two conditions were compared in the obtained seismic slope safety factor.The results show that the finite element strength reduction method is available in earthquake stability analysis of slope.
