摘　　要：针对佛山市南海区一汽大众生活区配套道路工程特定的场地特点,经分析比较,选用CFG桩复合地基对软土地基条件下的高填方路基进行加固处理,论文介绍了CFG桩复合地基计算方法,分析了CFG桩的桩长、桩径、桩间距对路基沉降的影响,综合考虑设计合理与经济性,最终确定CFG桩的桩径为0.5 m,桩长为8 m,桩间距为1.8 m。In view of the character of the site geology and environment condition in Faw-Volkswagen living area supporting road.Based on analysis of safety and cost,It comes to the conclusion that CFG pile composite foundation can be suit for subgrade strengthening in high-filled embankment.This paper introduces the calculation method of CFG pile composite foundation,analyzes the influence of CFG pile length,pile diameter and pile spacing on the subgrade settlement,and considers the design reasonable and economical,finally determines the CFG pile diameter of 0.5 m,pile length of 8 m and pile spacing of 1.8 m.
