摘　　要：CFG桩复合地基和夯实水泥土桩复合地基都是十分有效的地基加固技术 ,但很少有将两者组合应用于地基处理中。本文介绍了将这种组合方法应用在某项工程的地基加固中 ,分析了两种桩的承载机理和特性 ,阐述了其方案设计和承载力计算公式。结合工程实例 ,通过现场原位试验 ,表明了其良好的加固效果。实践证明该技术在新近堆积黄土地基中的应用是可行的 。Both composite foundations of CFG piles and compacted cement-soil piles are very effective methods of foundation consolidation technology.But the use of the two kinds of piles as a combined composite base was seldom found in the treatment of foundation.So, the combination of the two kinds of piles was used by authors in an engineering project.Meanwhile,the bearing mechanism and properties of both two kinds of piles are analysed,and the design scheme and calculation formula are introduced. According to the project case and in-situ test, it is proved that this technology is feasible and can be used in newly-filled earth foundation.
