Abstract

This paper presents an optimal location design of steel pipe pile foundation by using the genetic algorithm (GA). The pile diameter and thickness, the distance between each pile, number of pile column and number of each pile column are selected as the design variables, and the minimum cost is selected as the object function. The optimal design problem is formulated as the discrete optimization problem by erasing the distance between each pile from the design variables on the characteristics of the optimal solution. The GA with selecting the crossing strings is used to solve it with the specific coading for GA strings.
