| Abstract: | A three-dimensional finite elements composite pile foundation model is established based on soil's elastoplastic and contact properties between piles and soil by finite elements program,the additional stress'changingtrend are analyzed by isograph under the effect of variation of pile's length L,diameter d of pile and distance S between piles which are calculated systematically. |
