摘　　要：通过具体算例,介绍了轴心荷载作用下独立基础CFG桩复合地基的常规设计方法,讨论了常规等承载力设计法的不足,并给出了根据天然地基承载力、单桩承载力优选桩数和基础面积的非等承载力设计方法。Through the examples,the traditional design method of CFG-pile composite foundation under isolated base bearing centric compression was introduced,and the disadvantages of the traditional design method were discussed.The unequal bearing capacity design method is proposed which chooses the pile number and foundation area according to the natural foundation bearing capacity and single pile bearing capacity.

关 键 词：复合地基 CFG桩 非等承载力 中心受压
