摘　　要：首先对单桩有限元计算模型进行了论述,然后用有限元法分析了褥垫层模量、垫层厚度、桩的长径比等因素对CFG桩复合地基沉降的影响,并指出褥垫层是CFG桩复合地基的核心技术,最后得出了一些有意义的结论。Firstly it expounds calculative model of singte pile limited unit, then analyzes the influence of factors, such as mattress-cushion layer mould capacity, thickness of cushion layer and length-diameter ratio of pile to CFG pile composite foundation subside from using limit unit method, and indicates that mattress-cushion layer is a nuclear technique of CFG pile composite foundation, finally reaches some significant conclusions.
