摘　　要：分析了滑坡成因,并对其稳定性进行了评价。融深层侧向位移监测于工程地质勘察,明确了滑坡的主滑方向,准确定位了主滑动面。现场取样,经土工试验,确定了滑带土的密度ρ、内聚力c的取值。通过反分析法,在安全系数k=0.95的条件下,反算内摩擦角φ的取值。根据滑坡剩余下滑力的大小,创造性地建立了h型抗滑桩模型,对滑坡进行分区综合治理,并取得了良好的效果。该滑坡的成功治理方案,为治理大推力滑坡提供了宝贵的借鉴。The cause of slope is analysised, and an evaluation is taken on its stability. Combining deep crossrange displacement monitoring with engineering geological investigation, the main sliding direc- tion is clear and the mayor slip surface accurately positioned. By soil test of after field sampling, the den- sity p and the cohesion c of slip zone soil are determined. Through the method of anti-analysis, on the condition of the safety factor k = 0.95, the value selection of angle of internal friction q~ is figured out. According to the rest push, the model of h form anti-slide pile is creatively established. And it has a good effect by Partitional comprehensive treatment. This is a successful improvement scheme, which will be of reference value for other landslide treatment practices of large rest push.
