基于遗传算法的基坑土钉支护整体稳定性求解

摘要

The most dangerous slip surface was automatically searched and calculated the corresponding coefficient of stability in soil-nail of a foundation pit by Genetic Algorithm and Visual c ＋ ＋6.0 programming, the paper discusses the impact of Pc and Pm value upon convergence rate. The results calculated by the Genetic Algorithm determine is same by the traditional calculation, and consistent with the monitoring results. Therefore it is proved that this method is effective and accurate.%结合遗传算法和Visual c＋＋6.0编程对某基坑的土钉支护的最危险滑动面进行了自动搜索并计算了对应的稳定性系数,讨论了pc和pm的取值对收敛速度的影响,结果表明遗传算法所确定的最危险滑动面与传统计算结果相符合,并与监测结果吻合,证明了该方法的有效性和准确性。
