禹门口提水东扩工程一级泵站出水池地基处理

摘要

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.%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。
