摘　　要：CFG桩,即水泥粉煤灰碎石桩,是在原碎石桩的基础上加入适量粉煤灰、石屑和少量水泥,加水拌和后制成具有一定强度的桩体。CFG桩复合地基它是由CFG桩、桩间土、褥垫层构成的复合地基。由于其具有施工速度快、工程工期短、工程质量容易控制、造价低、环境污染小的特点,已被列为住建部重点推广技术和国家科工委重点推广研究成果,已在全国多个省市和各地区工业建筑的地基处理中得到广泛的应用,目前已成为应用非常普遍的地基处理技术。CFG pile,namely cement fly ash gravel pile,is a pile body with a certain strength that is made by adding an appropriate amount of fly ash,stone chips and a small amount of cement on the basis of the original gravel pile,after water mixing.CFG pile composite foundation is a composite foundation composed of CFG pile,soil between piles,and cushion bedding.Because of its fast construction speed,short construction period,easy control of project quality,low cost and low environmental pollution,it has been listed as the key promotion technology by the Ministry of Housing and Urban-Rural Development and the key promotion research achievement by the State Administration of Science,Technology and Industry,and has been widely used in the foundation treatment of industrial buildings in many provinces,cities and various regions across the country,and has become a very common foundation treatment technology at present.
