摘要： 以武广高速铁路路堤CFG桩复合地基2个试验路段共28个断面的实测数据为依据，开展了路堤荷载作用下CFG桩复合地基沉降变形特性的分析，进一步结合分层总和法，获取了相应的沉降修正系数 ，由此得到了适用于高速铁路CFG桩复合地基的沉降计算方法，对完善高速铁路路堤CFG桩复合地基的设计技术具有参考价值。

Abstract: Based on the monitoring data of 28 sections of 2 work sites on Wuhan-Guangzhou High-speed Railway, the deformation characteristic of CFG pile composite foundation under embankment load was analyzed. The settlement correction coefficient   was obtained by using the layering summation method, so it was use to calculate the settlement of CFG pile composite foundation under embankment load, which could provide a useful reference for the similar engineering.
