| Abstract: | Applying the numerical analysis method of piled raft foundation in the layered soil,which is established by coupling the element-free method and the analytic model of pile-soil system,this paper studies the settlement system of variable stiffness piled raft foundations in different combination.The advantage and disadvantage of different layout are discussed.The result has a certain reference value to the optimization design of piled raft foundation. |
| Keywords: | piled raft foundation variable stiffness settlement pile-layout optimization |
