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.
