【摘要】 基于边坡的斜条分法上限解,使用累加弦长三次样条曲线模拟边坡的滑裂面。在搜索最小安全系数所对应的临界滑面时,利用圆率法修改原始型值点列以达到曲线光顺的目的,以此作为免疫遗传算法中的接种疫苗这一遗传操作提高了各群中的个体适应度,从而最终提高了遗传算法的解题效率。更多还原

【Abstract】 A study on immune genetic algorithm(IGA) to determinate noncircular critical slip surface of slopes is carried out. According to the slope stability analysis by upper bound approach,the slip surface of the slope is simulated by cubic spline curves of accumulation chord.To make the curves smooth,the circle of curvature method is applied to search the critical slip surface corresponding to the minimal safety factor.And circle of curvature method,which is vaccination,is applied to improve the adaptation of the individuals and the efficiency of the solutions.更多还原
