桩箱筏优化设计的加速遗传算法

Accelerating Genetic Algorithms in the opt imizing design of pile-box-raft foundation

遗传算法作为一种全局优化算法,遗传算法克服了传统优化方法容易陷入局部最优值的缺陷。将新兴的交叉学科遗传算法引入到桩箱筏优化设计中,以桩箱筏的总造价作为优化目标函数,全部约束条件按《建筑桩基技术规范》(JGJ94-1994)给出,编制了桩筏优化设计计算程序,通过计算实例证明了遗传算法用于桩箱筏优化设计的可行性。

Traditional optimizing methods a re prone to get the partial best value , as a kind of holistic optimizing method, Genetic Algorithms get rid of this disadvantage.Ap plying the new cross technology Genetic Alg orithms to the optimizing design of pile-bo x-raft foundation .Take the whole cost of p ile-box-raft foundation as the target func tion , and all of the restriction according to 《Technical Code for Building Pile Founda tions》(JGJ94-1994). Design the calculate p rogram for pile-box-raft foundation. And p rove by example that the method used in this paper is effective .
