| 摘 要： | 根据遗传算法的思想和拟静力瑞典法基于圆弧滑动面的假定，提出一种用遗传算法搜索最危险滑动面及其对应的最小安全系数的方法。该方法模拟了生物遗传进化过程，克服了传统方法容易陷和局部极小值的缺点，是一种全局优化算法。并通过一个工程实例对其进行了验证。 |
| 关 键 词： | 遗传算法 边坡 抗震稳定性 最危险滑动面 最小安全系数 |

| Abstract: | According to the quasi-static seismic stability analysis of slope,a new method based on the assumption of circular slip surface is established.This method uses genetic algorithm to determine the most dangerous slip surface and the corresponding minimum factor of safety.The method can simulate the genetic evolutionary process of organisms and avoid local minimum value.It is a global optimal algorithm,so it has obvious advantages compared with the classical methods.This reasonable method is verified by a case study as well. |
| Keywords: | genetic algorithm slope seismic stability most dangerous sliding surface minimum factor of safety |
