| 摘 要： | 针对边坡稳定验算中极限平衡法和有限元法各自优缺点,采用有限元强度折减法对边坡进行稳定验算并结合Mohr-Coulomb准则通过自定义指标S反映土坡潜在的滑裂面。计算结果与实际情况吻合较好。

| Abstract: | Taking corresponding advantages and disadvantages of the limit equilibrium method and the finite element method into account,the paper analyzes the slope stability with shear strength reduction finite element method and derives the stress index S combined with the Mohr-Coulomb criterion,then analyzes the slope stability.The analytic results shows that the index S is useful. |
