| 摘 要： | 基于土质滑坡滑裂面的若干实例,总结出发生土质边坡滑裂面的一些规律。据此,提出滑裂面几何参数的若干统计规律。应用蒙特卡洛概念得出一系列滑裂面。用条分法分别确定出抗滑安全系数,安全系数最小的就是最危险滑裂面。通过实例验算,获得较为满意的结果。

| Abstract: | On the basis of several examples about slip fracture plane of soil landslide,some law about occurrence of slip fracture plane on soil slope were summarized,and some statistical law of geometric para meters of slip fracture plane were put forward. A series of slip fracture planes were obtained with Monte Carlo method. The safety coefficient of resistance to slip were determined respectively with finite slice method. The slip fracture plane with minimum safety coefficient is the most dangerous one . Through practical test,the result obtained was satisfied. |
