The Method of Determining the Most Critical Three Dimensional Sliding Surface of Soil Slope

文章基于均质土坡旋转椭球形滑动面的假设,提出了一种用遗传算法确定均质土坡三维最危险滑动面及其对应的最小稳定系数的方法。该方法模拟了生物遗传进化的过程,克服了传统方法容易陷入局部极小值的缺点,是一种全局优化算法。

According to the assumption of uniform soil slopes,the article introduces a method which uses genetic evolutionary algorithm to determine the most dangerous three dimensional sliding surface and the corresponding minimum safety factor.It simulates genetic evolutionary process of organisms and avoids local minimum value.It is a global optimal algorithm and has advantages over the classical method.
