| 摘 要： | 在对边坡的稳定性进行分析评价时,传统分析方法引入了滑裂面为圆弧型的假设;也有学者将滑裂面假定为对数螺旋线型等其它函数形式。由于边坡实际情况的千差万别,这些假定只能适合于部分特殊的边坡。为此本文利用遗传进化算法来搜索模拟边坡的非圆弧型最危险滑动面,提出了一种土质边坡稳定性分析的遗传进化调优算法,它是一种全局优化分析方法。有很好的重复性。且不依赖于目标函数的性质和边坡的具体形状。

| Abstract: | When analyze the stability of slopes, traditional methods often use suppose that the failure surface is circular or other typical functions. But because of complicated surroundings, these suppose only fit for some special questions. So this paper used GAs to search the non-circular critical failure surface, got a new optimization method for soil slopes, which is a global optimal algorithm with good character and don't depends on the shapes of slopes and the function's type. |
