Abstract

Abstract: It is available to get tlle critical slip of a slope and the minimum safe coefficient accordingly by optimal methods． Since a slip in a circle shape or in random shape could be described throush a group of parameters，the safe coefficient of a slope could be expressed as a function of the parameters．In this paper。discussed is a method to work out the minimum values of such fun ctions by combining optimal methods with classic ways in analyzing the slope stability．

Key words: optimal, slopestability, theminimumsafecoeficient

摘要： 边坡稳定性分析中相应于最小安全系数的临界滑裂面可以通过运用最优化方法求得．圆弧和任意形状滑裂面均可用一系列参数来描述，其安全系数则可表达为这些参数的函数．笔者运用最优化方法结合边坡稳定性分析的常用土力学方法求此类函数的极小值．
