摘　　要：滑坡稳定性分析及滑动推力的计算评价是滑坡地质灾害防治论证的重要基础,郴州市裕后街滑坡运用传递系数法计算其稳定系数可知,在天然状态下,稳定系数为～,饱水1.161.23状态下,稳定系数为～,说明在降水条件下不稳定。建议采用削方减载和挡墙抗滑的综0.890.98合治理方案进行防治。The stability analysis and calculation and appraisal of landslide thrust is the important basic proof of geological hazard prevention and cure of landslide. Based on the stability coefficient being calculated by the transmit coefficient method in Yuhoujie landslde of Chenzhou, we can know, while the stability coefficient is equal to 1.16~1.23, the landslide is in the nature situation, and is equal to 0.89~0.98, it is in saturated water situation, it states clearly the landslide is unstabile when it is raining. The authors suggest to adopt the comprehensive administration with cutting earthwork in order to reduce the upper load, and retaining wall in order to resist slide.
