| Abstract: | Based on the reinforcing mechanism of CFG pile composite foundation are expounded, on the background of a certain spoil retaining wall project, it explored replacement cushion method,sand stone pile method and CFG pile applied to powdery clay foundation reinforcement treatment, and used the standard method of calculation. The results show that： low replacement rate of application of CFG pile composite foundation powdery clay foundation reinforcement is feasible, it can meet the require- ments of the foundation bearing capacity and settlement. |
