| 摘 要： | 在遗传算法和瑞典条分法的基础上,提出了对边坡临界滑裂面的搜索方法及其最小安全系数的求解方法.文中利用安全系数的倒数作为目标函数,可行域根据实际边坡的尺寸和经验给出,而且在计算过程中根据目标函数值进行调节,逐步缩小搜索空间,使搜索效率提高.算法中利用了十进制遗传算法的改进操作优体克隆操作和子体优生操作,提高了搜索的速度和精度.

| Abstract: | Based on genetic algorithm and Sweden method of slices,this paper puts forward the searching methods of critical failure surface and minimum safety factor in slope.Using reciprocal of safety factors to be objective function,according to the size of slope and experiences of engineer,feasible field has been set up,which could be adjusted upon the value of objective function by dwindling the searching band to improve the search efficiency.It can be used to boost the searching speed and to improve the searching precision to apply the improved genetic operation: operation of the best chromosome clone and younger generation chromosomes prepotency in algorithm programming. |
