The wind power generation

as one of the fastest-growing new energy

gets more and more attentions. The optimizational design of wind turbine foundations under coupled loads becomes an important issue. In this paper

the accuracy and the ability of a finite element method to simulate the load coupled effect are verified through comparisons with published results. Then a piled beam-raft foundation of Guohua Tongliao wind farms is analyzed using finite element method. The research mainly focuses on the stress and deformation characteristics of the pipe piles

rib beams and the ring beam of the foundation under coupled loads. The internal forces of them are compared with those from design. At the same time

this paper analyzes the pile-soil-sharing ratio of the wind turbine foundation and investigates the bearing role of soil under coupled load. The results provide a reference for the actual engineering design.
