| 摘 要： | 本文通过采用有限元强度折减法对某边坡进行了稳定性分析,分析结果表明:随着折减系数的不断增大并达到某一数值时,边坡内广义剪应变自坡底向坡顶贯通,边坡达到极限状态,此时的折减系数即为安全系数。表明有限元强度折减法对边坡稳定性分析具良好的适用性。 |
| 关 键 词： | 强度折减 边坡 安全系数 稳定性 |

| Abstract: | The strength reduction FEM is used to analyze the stability of a slope in the paper,it is found that a well defined failure shear strain zone is formed in the slope with the factor of strength reduction increasing and reaches some value,the slope reach the limit.Now the factor of strength reduction is equal to the safety factor,it is concluded that the method is appropriate for stability analysis of slope. |
| Keywords: | strength reduction slope safety factor stability. |
