| 摘 要： | 文中阐述了强度折减的有限元方法求解边坡稳定的安全系数的分析方法,分析了屈服准则对计算边坡稳定的安全系数的影响,算例表明采用有限元方法来求解边坡稳定安全系数产生误差大的主要原因是屈服准则的选取。并对糯扎渡大坝的两种设计方案进行了分析,结果表明了该方法的可行性。

| Abstract: | The authors presented the finite element method of strength reduction for solving the safety coefficient of slope stability. The effect of the yielding criterion on the slope stability safety coefficient was analyzed. It showed that the yielding criterion had great effect on the slope stability. The method was applied to analyze the slope stability of two design schemes of the Nuozhadu dam and the results proved the feasibility of its application in practical engineering. |
