Abstract: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.

Keywords:pile foundation; optimal design; chaotic particle swarm algorithm; foundation cost
