研究现状表明基本遗传算法应用于边坡稳定性分析时存在局部搜索能力差、容易陷入早熟的缺陷。通过分析提出一个动态杂交率和动态变异率的计算公式对基本遗传算法进行改进，编制了基于改进遗传算法的边坡稳定性分析程序。对一个边坡算例进行了稳定性分析验算，该算例表明改进遗传算法具有更强的全局搜索能力和收敛能力，搜索效果更好。

Present research on the application of the basic genetic algorithm in slope stability analysis shows that the method has poor local search capability and it is prone to premature failures .Here ,a formula which was used to calculate dynamic crossover rate and dynamic mutation rate was proposed to improve the basic genetic algorithm .And then a pro-gram of slope stability analysis was developed based on the improved genetic algorithm .It is proved that the improved ge-netic algorithm has a stronger ability of global search and better convergence ability ,based on its stability analysis of a slope .
