| Abstract: | A study on a representative pile group compound foundation by using 3-dimensional nonlinear stress and deformation analytical program is introduced in this paper. By comparison between various computational schemes, the discussion includes working mechanism and characteristics of stress and deformation for deep mixing pile compound foundation and the effect of load level, pile length, replacement, distribution of soil layers, deformation modules of piles on foundation settlement, stress of pile top, pile bearing capacity ratio. |
