摘　　要：　斜坡失稳灾害是建设用地地质灾害中最常见的灾害类型之一,准确的预测评估是至关重要 斜坡稳定性的预测方法很多,主要有过程机制分析法、理论计算法、工程地质类比法及影响因素加权平均值法等 由于各种方法均有其适用条件和局限性,因此文中着重介绍适用性及操作性较强的影响因素加权平均值法,对影响斜坡稳定性的各因素逐一进行了分析。Unfirm Slope Disaster is one of the geological disasters commonly seen in the land use for construction, the forecast estimate to it correctly is very important. There are some of the forecast methods to the slope stability. The major methods are the process mechanism analyzing, the theory calculating, engineering geology comparing, affect factor weighted average and so on, because of the conditions and limitation of all kinds of the methods them self, this paper describes the method of the affect factor weighted average value that is applicable and operatible, and also describes and analyzes each factors affecting the slope stability step by step that has been tested and verified in the engineering projects.
