| Abstract: | Numerical emulation experimentations are carried out on the bearing performances of the single dry-cement jet mixing pile composite foundation by means of the finite element method (FEM). The load transferring rules of the single pile in the composite foundation and the variation of stress ratio of pile-soil during loading process are analyzed, and the influences of cushion layer on the stress ratio of pile-soil are analyzed. |
