| 摘 要： | 基于极限平衡分析法和有限元法,对同一边坡进行了稳定性考察。对比计算表明,有限元计算得到的边坡安全系数与极限平衡法的结果非常接近。有限元计算还可以提供边坡坡体内的主应力、最大塑性应变、塑性区、水平位移、竖向位移、总体位移增量等参量的分布情况,为边坡加固方案的确定与加固位置的选择提供了依据。

| Abstract: | The stability analysis of a slope was made respectively using limiting equilibrium method and finite element method(FEM).Through comparison,it was found that the slope safety factors obtained by the two methods are almost the same.The distribution of principal stress,maximal plastic strain,plastic zone,horizontal displacement,vertical settlement and increment of displacement can be investigated by FEM effectively,which can provide a basis for the determination of reinforcing scheme and positions of slope. |
