摘　　要：将遗传算法应用于边坡工程的分析和设计,若边坡滑动面为圆弧状,可搜索出圆弧形临界滑动面的圆心及滑出点坐标,从而确定了临界滑动面的位置,并利用简化毕肖普法和瑞典法求出对应的抗滑稳定安全系数,实现了遗传算法在边坡稳定分析中的应用.通过计算实例证明,遗传算法在边坡稳定分析中具有一定的适用性及优越性.The genetic algorithm is used to analysis and design of the slope stability, if the shape of slope surface is circular arc then it can search the location of circle critical slip surface （consist of coordinates of the center and the point which slip off the surface）, so as to determine the safety factor of stability of the slope employing the method of Bishop and Fellenious. The living example shows that the genetic algorithm is ascendant and suitable to the stability analysis of the circle slope with circular slip surface.
