| 摘 要： | 结合经典的土坡算例进行边坡稳定性计算，运用有限元强度折减法分别建立二维和三维模型．并把有限元强度折减法的计算结果与刚体极限平衡法（Spencer法和Bish叩法）的计算结果进行比较，结果表明有限元强度折减法能满足工程应用，值得推广。

| Abstract: | One classical soil slope case is studied in slope stability. Finite element strength reduction method is applied to set up two-dimensional and three-dimensional models, and the calculation results between the finite element strength reduction method and the rigid limit equilibrium method （Spencer method and Bishop method） are compared. The results show it can meet the demand of projects, worthy of popularization. |
