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。
On the basis of ordinary slice method for stability analysis of rock and soil slope, genetic algorithm (GA) which searches the optimal solution by simulating natural evolution process is used to determine the most dangerous slip surface. A new method is proposed for reliability of rock and soil slope This method overcomes the shortcomings that the traditional tuning analysis method is easily trapped in the local optimal solution. It is suitable for the search of various objective functions and the critical slip surface of the complex earth slope. Finally, the method is applied to the reliability analysis of the exposed slope of Yaman Cycas mine in Xinjiang, and the satisfactory result is obtained.
