| 摘 要： | 以极限平衡理论为基础,假定滑动面为圆弧面或近似于圆弧面,采用Bishop法,考虑竖向条间剪力对滑移面抗剪强度的影响,建立了滑坡最危险滑移面的搜索模型,并推导了稳定系数的求解公式;运用遗传算法对支挡结构最危险滑移面进行动态搜索和确定,计算其稳定性系数,避免了在优化设计中陷入局部最小值的缺点,使其结果更具有效性和准确性。

| Abstract: | Based on ultimate equilibrium theory,supposing sliding surface as a circular surface or similar to a circular surface,considering the influence of vertical shear on sliding surface shearing resistance,the searching model of the most dangerous sliding surface is established using Bishop Method and the solution formula of stabilizing coefficient is educed.The most dangerous sliding surface of supporting structure is searched dynamically and determined using genetic algorithm and its stabilizing coefficient is obtained to prevent involving in local minimum in optimization design to make the result more valid and precise. |
