| 摘 要： | 以国内应用广泛的毕肖普条分法结合MATLAB优化工具箱中具有优良特性的拟牛顿法和单纯形法编程,同时实现用这几种最优化方法求解最小安全系数,并就有关方面予以比较并查看它们的求解差异,以期通过多种方法的比较尽可能地找到真正的危险滑裂面。考虑到初值的选取对优化计算的重要影响,适当地采用了一些合理的方法。

| Abstract: | Considering the excellent optimization toolbox in MATLAB,this paper combines the good-attributes quasi-Newton method and the simplex method in MATLAB toolbox with the popular bishop method to achieve the min safety factor and conducts further a comparison in some terms,hoping to find the real minimum safety factor.Considering the important role that the original value plays,we adopt some reasonable methods. |
