摘要
基于遗传算法中处理约束条件使用的传统罚函数方法效果并不理想,本文提出了一种处理约束优化问题的模糊罚函数遗传算法,并在高层建筑的上部结构与地基基础共同作用的基础上,将其应用于高层建筑的桩箱基础的优化设计问题,工程实例证明其不仅能改善基础受力情况,而且具有较大的经济效益。
Because GA is a stochastic searching method, there are large differences between GA and the traditional methods, in dealing with constraints and the traditional methods are not suited for the integration with GA. In this paper, a fuzzy theory is used to deal with the constraint conditions and the fuzzy penalty function GA, that is a new method, was presented. This method is used in optimal design of engineering structure, and the effect is proved very good.
