摘　　要：以沪昆客专贵州玉屏某路基段地基处理工程为例,针对路基基底岩溶发育的工程地质问题,采用CFG桩复合地基方案进行加固处理,进行了CFG桩复合地基承载力的设计验算和处理效果检测,在对工程地质条件研究分析的基础上,较为系统地提出了各种不同的岩溶工程地质条件下CFG桩设计和施工的应对措施。This paper takes one segment of subgrade ground treatment engineering of Shanghai-Kunming passenger line guizhou section as studycase,which adopts CFG pile composite foundation aiming at the karst development in basement of subgrade,calculation of CFG pile composite foundation bearing capacity and testing of treatment effects are carried on.On the basis of research and analysis of engineering geological condition,corresponding countermeasures for design and construction of CFG pile under different karst engineering geological condition are proposed systematically.
