Abstract：Research purposes：Rammer carrier CFG pile composite foundation is increasingly used widely, but only a little theoretical research has been done on it. Combined with one engineering practice of rammer carrier CFG pile composite foundation, this paper researches the influencing regulation of the different loads, single pile carrying capability, cushion layer depth, pile length and space between piles on the bearing capacity and deformation of the foundation with the monitored date on rammer carrier CFG pile and FLAC software.
Research conclusions：From the research on the sensitivity of such new composite foundation to the all parameters, it is concluded the effective range of the negative friction of rammer carrier CFG pile is wider than the common CFG pile , and the neutral point is very low or zero. The effect of pile body of rammer carrier CFG pile is more obvious and the cushion of rammer carrier CFG pile composite foundation should be thicker than common CFG pile composite foundation.
