| Abstract: | A set of approximate analysis formulas of pile-soil system in rigid pile composite foundations is derived.The element-free method is used to simulate the raft on the composite foundations,and the finite element method to solve the cushion.A computation method of raft foundation on variable stiffness rigid pile composite foundations is established by coupled the pile-soil system and the cushion as well as the raft,based on the displacement continuity.The reasonability and reliability of the proposed method a... |
