摘要
在土坡应力场非线性有限元分析的研究基础上,将蚂蚁算法这一新的启发式人工智能型优化方法与土坡稳定性有限元分析方法相结合,探讨了基于有限元分析得出的土坡应力场所对应最小稳定安全系数的土坡任意形状临界滑动面的蚂蚁算法搜索技术,并通过分析算例说明这一技术的可行性。
Based on the researches on the nonlinear finite element analysis of stress fields in soil slopes, the nonlinear finite element techniques for analysis stability of soil slopes is integrated with a ant algorithm, which is a new optimization method of artificial intelligence. The ant algorithm optimization technique is used in search of the non-circular slip surface associated with the minimum safety factor of soil slope based on its stress fields from finite element analysis. Finally the feasibility of the technique is demonstrated with an example of stability analysis.
