摘　　要：结合工程实例,利用Geo Slope岩土软件对一土质边坡稳定性系数分别采用极限平衡法中的瑞典法(Fellenius/Petterson)与毕肖普法(Bishop)、不平衡推力法(隐式)和不平衡推力法(显式)进行了分析,并用数值计算软件FLAC对边坡稳定系数进行计算,分析了各种方法的差异和产生原因,并提出建议。Combining with engineering example,adopting Geo Slope geotechnical software,the paper analyzes the soil slope stability coefficient by using Fellenius/Petterson in limit equilibrium method Bishop,imbalanced thrust force method（ stable style） and imbalanced thrust force method（ apparent style）,calculates the slope stability coefficient by applying numerical calculation software FLAC,analyzes their difference and similarities of various methods and causes,and finally puts forward some suggestions.

关 键 词：边坡稳定性 极限平衡法 有限差分法
