摘要
结合湿陷性黄土地区大型油罐工程,对DDC灰土挤密桩从加固机理、受力特性、承载力和沉降计算等方面进行了深入研究,提出了帷幕桩和帷幕内桩的划分概念。实践表明,利用不等长DDC灰土挤密桩对湿陷性黄土地基进行处理,能较大幅度地提高地基承载力,消除黄土的湿陷性,节约工程造价,为湿陷性黄土地区油罐基础提供一种可行的地基处理方案。
On the basis of introduction to large oil tank project in collapsible loess area,the article makes deep research of enforcement mechanism, bearing eapaeity and settlement ealeulation for the DDC lime-soil pile, and presents the concept of distinguishing curtain pile from the pile inside curtain. Practice shows that the method of using different length of DDC lime-soil to treat collapsible loess can greatly improve the bearing capacity of foundation, eliminate eollapsibi｜ity and save construction cost. It provides a feasible foundation treatment program for oil tank projeet in collapsible loess area.
