The weak structural plane is one of the key factors that control the stability of slopes,it not only controls the sliding surface position and geometry,but also directly affects the results of slope stability analysis,a new method called simplex-finite stochastic tracking method was provided. Combining with an engineering example,introduced the process using this method searching the sliding surface. According to the meth-od we can get the position of slope potential sliding surface when the slope there is potential sliding surface. What is more,the potential sliding surface can reflect the engineering geological condition and the results of the stability analysis more reliable.%针对边坡内置软弱结构面直接控制着边坡临界滑动面的位置和几何形状，并影响边坡稳定性分析结果的问题，提出了单纯形—有限随机追踪法，并结合工程实例，介绍了该方法搜索滑动面的过程，指出其可有效搜索得到内置软弱结构面边坡滑动面位置，并可在反映工程地质条件的基础上得出可靠的计算结果。
