以某高层住宅楼地基处理工程为例,介绍了灰土挤密桩处理湿陷性黄土地基的基本原理,并用此原理对本工程进行了设计,设计结果和质量检测表明：消除了其部分湿陷量,形成的复合地基承载力较高,满足了设计要求。%Taking the foundation treatment project of some high-rise building as the example,the paper introduces the basic principle for the treatment of collapsible loess foundation by the lime-soil compaction pile,designs the project based on the principle,and proves by the design results and the quality detention that the partial collapse settlement can be eliminated,the bearing loading capacity of the composite foundation can be formed and the design requirements be met.
