摘要
在岩土边坡稳定性分析普通条分法的基础上，通过模拟自然进化过程搜索最优解的遗传算法（ ＧＡ） ，确定最危险滑动面，提出了一种适用于岩土边坡可靠性分析的遗传进化全局调优分析方法，克服了传统调优分析方法容易陷于局部最优解的缺点，适合于各种目标函数和土性复杂边坡临界滑裂面的搜索。最后，将该法应用于新疆雅满苏铁矿露采边坡可靠性分析，取得了满意的效果。
Based on the genetic algorithm and limit equilibrium method of slope stability analysis, a global optimal algorithm suitable for evaluating the reliability of rock slope or earth slope is established in this paper. Since this optimization method can overcome the shortcomings that result from traditional optimization methods, it is suitable for searching for all objective functions and critical slip surfaces of slopes with a complex earth property. This method has applied in the slope stability analysis of Yamansu Iron Open pit, Xingjiang, and obtained satisfactory results.
