| 摘 要： | 在土坡稳定分析的经典极限平衡法中,一般先假设土坡的最危险滑裂面形状,然后利用不同的搜索方法寻求最优解。作者认为,基于经典极限平衡理论的边坡滑裂面是由土条底部的直线段相连构成的任意形状滑裂面;定义土条底部的纵轴坐标或者与水平面的夹角为搜索变量,采用经验遗传-单纯形算法搜索其最优解,进行了土钉加固土质边坡的稳定性验算,与圆弧滑裂面法进行了比较分析,结果表明作者的方法合理可行。

| Abstract: | During analyzing the stability of soil slope with conventional ultimate balance method,the slope shape of sliding-plane need to be assumed firstly,then different methods are used to search the optimum solutions.In this paper,it is assumed that the shape of sliding-plane is arbitrary based on the conventional ultimate balance method,and it is formed by the end-to-end line of soil strip bottom during analyzing the stability of slope;the longitudinal coordinates of soil strip bottom or the angles between soil ... |
