摘要
对土坡圆弧滑动面的搜索可以简化为圆心坐标及半径的搜索问题,而非圆弧滑动面的搜索,也可简化为滑动面上若干关键点坐标的搜索问题。因此,土坡潜在滑动面的搜索可变成一个典型的复杂连续函数优化问题。本文就此提出一种新的解决连续函数优化问题的连续型蚁群算法,它具有简单易实现且计算效率高等特点,特别适用于复杂工程优化问题。最后,通过一个典型算例进行验证,并与遗传进化算法比较表明,本算法的计算效率较高。
The search of critical surface of circular slip in soil slope can be transformed into the search of coordinates of circle center and its radius. While in non-circular slip, the search of slip surface may be transformed into the search of coordinates of references points at the surface. Thus, such searches are typical optimizations of complicated continuous functions. A new method namely Continuous Ant Colony Algorithm is introduced to solve this problem. An example is given for demonstrating the validity of this method. The comparison with genetic evolution algorithm shows that the proposed method has higher efficiency.
