演化算法寻找地基稳定性最小安全系数的实现

Utilization of evolvement arithmetic in routing foundation stability minimum safety factor

从演化计算中的遗传算法思想出发,构造了一个寻找最小安全系数的控制收敛矩阵。由该控制收敛矩阵4个角点的安全系数的大小决定下一个控制收敛矩阵移动的方向。当该矩阵的安全系数在型心为最小时,运用二分法将控制收敛矩阵尺寸减小一半进行计算,直到满足要求为止。并结合一个具体的工程,给出了在寻找最小安全系数的过程,验证了文中所给方法的可行性。

<Abstrcat>Based on the genetic algorithm idea of evolvement calculation, a control convergent matrix for routing the minimum safety factor is designed. The magnitude of the safety factor at 4 corner points of the previous control convergent matrix will determine the movement direction of the next control convergent matrix. When the minimum safety factor is at the center of matrix, the control convergent matrix shall be reduced by half by means of dichotomy before subsequent calculation until meeting requirements. Taking a practical project as example, the authors show the course of routing the minimum safety factor and demonstrate the feasibility of the method introduced in their paper.
