基于湿陷性黄土的特有工程特性，采取经济合理的技术措施对其进行加固、治理，消除其湿陷性，提高承载能力，控制地基变形，可以最大限度地降低其危害。采用灰土挤密桩和CFG桩多桩型处理湿陷性黄土地基，通过桩土共同作用，既发挥了灰土挤密桩的挤密效果，达到消除黄土湿陷性的目的，又充分发挥了CFG桩的高承载力性能，提高抗变形能力，处理效果明显，具有推广价值。

Based on the special engineering property of collapsible loess ,the economic and reasonable technical measures are taken for reinforcement and governance,to eliminate its collapsibility,improve the bearing capacity, control the deformation of foundation,and finally minimize its harm. We disposed the collapsible foundation with a muti-pile type of lime-soil compaction pile and Cerment Fly-ash Grave. Through the interaction of pile and soil , not only the loess collapsibility is eliminated by the compaction effect of the lime-soil compaction pile ,but also the deformation ablity is improved by the high capacity performance of CFG. The effect is obvious and the type has the value for expansion.
