摘要： CFG桩是由适量水泥、碎石、石屑或砂、粉煤灰加水拌合而成的高粘结强度桩，它和桩间土、褥垫层一起形成复合地基，充分利用桩间土的承载力，共同作用，可将荷载传递到深层地基中去，具有较好的技术性能和经济效果。结合工程实例，介绍了CFG桩复合地基在地基处理中的具体应用。

Abstract: CFG pile is a kind of high strength pile with good adhesiveness which is the mixture of cement, gravel, stone chips or sand, fly ash with water, it is combined with soil between piles and cushion into the composite foundation, in which the bearing performance of soil between piles is fully used and the load is transferred to the deep stratum by the cooperation between piles and soil between piles. The CFG pile composite foundation has good technical performance and economic effects. Based on the engineering, its application is introduced in ground treatment.
