PSO Algorithm can search the extreme point of the complex objective function more effectively in contrast to tradition optimization algorithm. Based on PSO algorithm and geometric implication of the reliability index, a global optimal method is put forward to calculate the reliability index. In recently years, multi-pile composite foundation is widely used. The classification and the computation methods of bearing capacity of multi-pile composite ground are generalized, and the ultimate bearing capacity equation is deduced in this paper. The PSO algorithm is used in reliability analysis of multi-pile composite foundation. The program of computing reliability index is developed in MATLAB. Three practical examples using Monte-Carlo method and PSO algorithm show that PSO algorithm has the advantages of rapid convergence and high perecision in the reliability analysis of bearing capacity of multi-pile composite ground.
