| Abstract: | This paper discussed the bearing capacity and deformation behavior of CFG(cement fly-ash gravel)pile composite foundation with numerical analysis method. By comparison between different schemes computation, the pile-soil stress ratio and the loading distribution rule between pile and soil were analyzed, according to the effect of different load level, pile length, replacement ratio, soil layers and deformation modules of pile. |
