| Abstract:This paper made a thorough study on the bearing performances of the composite foundation by means of the finite element method (FEM). First it analyzed the loading transfer of the general single pile and the single pile of the composite foundation. Then the distribution laws and characteristics of the lateral friction force in the group pile effect and the top pre stresses and the additional stresses of pile are studied. The results of this research would provide a theoretical basis for rational design in the composite foundation. |
