| 摘 要： | 对一给定的滑坡（即滑坡坡率、坡高等已确定），稳定系数的影响因素有滑带土粘聚力、内摩擦角、滑体容重和孔隙水压力等。由于各因素对稳定系数的影响程度不同（即敏感性大小不同），因此，需要以定量的标准来找出其中影响较大的因子，作为滑坡治理重点研究的对象，有效提高滑坡整治效果。本文以延安市宝塔区王良寺滑坡为例，采用正交分析法对滑坡稳定性的影响因子进行了分析，并计算出各种组合的滑坡稳定系数，然后采用极差分析对因子进行敏感性评价；以分析结果为基础，提出滑坡的治理方案，以期达到经济合理的治理效果。 |
| 关 键 词： | 滑坡 稳定性 正交分析法 敏感性分析 治理措施 |

| Abstract: | The factors influencing landslide stability coefficients include cohesion of soil in the slide zone,internal friction angle,unit weight of the slide and the pore water pressure,etc.They affect the landslide stability coefficients in different degrees,so that one imposing the greatest influence on the landslide stability coefficients needs to be recognized by quantitative criteria,and studied more closely,to improve treatment effect.In this paper,all the factors are analyzed by using orthogonal analysis meth... |
