摘　　要：推导了以滑面圆心坐标为参数的均质简单边坡Bishop计算式,采用单纯形算法搜索该类边坡的临界滑裂面,编制了搜索临界滑面软件,用于海南横线万宁—儋州—洋浦高速公路某深挖路堑边坡,实践证明,单纯形算法可快速、准确的搜索到临界滑面。The paper deduces simple slope Bishop calculation formula with slip circle coordinate as the parameter, the paper applies simplex algorithm to explore its critical slip surface, formulates its critical slip surface software, and applies it into the deep excavation cut slope of Wanning- Danzhou-Yangpu on Hainan highway line. Practice proves that： simplex algorithm can fast and accurately explore the critical slip surface.

关 键 词：单纯形 临界滑面 高速公路
