摘要
为提高桩基础设计工作的效率及质量,将一种混沌粒子群算法引入到桩基础优化设计中。建立了以桩基础造价为目标函数的桩基础优化设计数学模型。编制了此数学模型的优化设计计算程序并对桩基础工程算例进行分析,从而得到了桩基础的若干主要参数对其造价影响的基本规律,证明了本优化方法具有可行性及比普通算法的优越性。
In order to improve the efficiency and quality of the design of pile foundations,a chaotic particle swarm algorithm was introduced in the optimal design of pile foundations. The mathematical model of pile foundation optimization design that takes pile foundation cost as objective function was established. A calculation program corresponding to the model was coded and a typical pile foundation engineering case was analyzed,and the basic rules of influences of main design parameters on the cost of pile foundations were then obtained,which demonstrated the feasibility of the optimal method as well as its advantages to those commonly used methods.
