湿陷性黄土地基含水量大、饱和度高，因而成孔后极易缩颈。利用长螺旋钻机成孔，采用适当填夯，按照先外排后里排的顺序、隔行隔点施工、分四遍完成的强力夯扩挤密灰土桩技术，通过事实案例检测，处理后的地基各项相关指标均佳，从而为提高湿陷性黄土地基的承载力提供了新途径。

Collapsible loess foundation is very easily slumping because of its rich water and high saturation. After long helical drilling, appropriate fillings are adopted. And then consolidate the compacted lime pile from outside to inside at certain intervals and for four times. The subsequent results obtained from an actual case are proved to be favorable. This provides a new way to improve the load bearing of collapsible loess.
