摘　　要：本文根据现场试验结果,对CFG桩复合地基承台与地基土间褥垫层的作用,垂直荷载下桩身竖向荷载传递特性及其加固效果进行了探讨。最后列举了CFG桩处理软弱地基的工程实例。Based on the outcome of field experiment, the function of cushion course between foundation and piles in composite ground, transmission behaviours of stress in pile shaft under vertical loads and the effects of soft clays improved with cement fly-ash gravel piles are investigated in this paper. Finally,engineer ing examples of soft clays treated with cement fly-ash gravel piles are listed.
