挤密桩加CFG桩在黄土地区地基处理中的应用

摘要

结合黄土的特点,介绍了挤密桩加长螺旋CFG桩的适用性及采用挤密桩加固湿陷性黄土地基的工作机理,分别阐述了挤密桩和CFG桩的设计要点,并结合实例对该施工技术的具体应用作了简要说明,指出其具有一定推广价值。%Combining with the characteristics of loess,this paper introduced the applicability of compaction piles and lengthened spiral CFG pile and the work mechanism using compaction pile strengthening collapsible loess foundation,separately elaborated the design features of compaction pile and CFG pile,combining with the example made briefly introduction to the specific application of this construction technology,pointed out it had certain promotion value.
