| Abstract: | In order to obtain the bearing characteristics of CFG composite foundation,based on the analysis of reinforcement mechanisms of CFG pile,the concrete courses of design and calculation for CFG composite foundation are introduced and the FEM model for CFG composite foundation is built under the engineering background.The validity and reasonability of FEM model and its parameters are verified by the comparison of computed and tested curves.Then the stress and deformation of CFG pile are obtained.Last the pile-... |
