灰土挤密桩地基是由回填夯实的灰土桩（按一定比例配制）和桩间挤密土共同组成并承担上部荷载的一种人工＂复合地基＂。通过地基处理以提高地基土的密实度,改善地基的承载力,提高地基的变形模量,消除地基土的湿陷性。文中通过对禹门口提水工程一级泵站出水池湿陷性黄土地基的处理,论证了灰土挤密桩在处理湿陷性黄土地基中的应用。
灰土擠密樁地基是由迴填夯實的灰土樁（按一定比例配製）和樁間擠密土共同組成併承擔上部荷載的一種人工＂複閤地基＂。通過地基處理以提高地基土的密實度,改善地基的承載力,提高地基的變形模量,消除地基土的濕陷性。文中通過對禹門口提水工程一級泵站齣水池濕陷性黃土地基的處理,論證瞭灰土擠密樁在處理濕陷性黃土地基中的應用。

The lime-soil compaction pile foundation is a man-made complex foundation,which is composed by pounded backfilled lime-soil piles with compacted soil among piles to bear the load on the foundation.By means of this foundation treatment measure,the density of foundation soil can be increased,the bearing capacity of foundation can be improved,the foundation modulus can be raised and the collapsibility of foundation soil can be eliminated.In this paper,through treating collapsible loess foundation of N0.1 pumping station＇s outlet sump of Yumenkou Easterly Extension Water Diversion Project,the application of lime-soil compaction pile of treating collapsible loess foundation is demonstrated.
