中文摘要:分析了路堤荷载下CFG桩复合地基的变形机理，根据假定的沉降模式及桩侧摩阻力分布形式，推导出了考虑桩-土-褥垫层共同作用的简化沉降计算公式，结果与试验数据吻合较好。

Settlement Analysis of Composite Ground Improved by CFG Piles under Road Embankment
Abstract:This paper analyzes the deformation mechanism of CFG pile composite ground under road embankment. Based on the assumed settlement model and the distribution of friction of pile, a method for settlement calculation of the interaction of pile-soil-cushion is deduced. A trial case shows that the predictions given by the derived formulas agree well with field measurements.
