| Abstract: | The numerical evaluation experiments on the single dry-cement Jet mixing pile composite foundation is made by means of the finite element method (FEM). The loading transfer and settlement of the single pile in the composite foundation and the variations of stress ratio and settlement of pile-soil are analyzed during loading process,and the influences of the modules of pile and cushion layer on the stress ratio and settlement of pile-soil are analyzed. |
