| Abstract: | The interaction between pile cap and soil plays very import roles during the design and calculation of pile group.In this paper,a three dimensional nonlinear numeric model of the coupled finite element-infinite element-contact interface element is established to analyze the interaction between pile cap and soil under different pile length,number of piles and so on.In the end,several pieces of advice on the design of pile foundation are proposed. |
