南水北调高填方堤基加固素土挤密桩施工技术简

南水北调中线漳古段永年县桩号74＋660--75＋095段在筑堤完成后发现黄土地基具有湿陷性，如采用传统的处理方式（强夯和翻压）处理，即影响工期又会对附近村民及房屋造成影响。采用土挤密桩处理，可以有效地改善地基土的物理性质，消除黄土地基的湿陷性，同时施工设备简单，节省了大量的开挖和回填工程量，节省了施工投资，缩短了施工工期。

Soil Construction Technology of Compaction Pile of High Fill Foundation Reinforcement in the South to North Water Diversion Project

The South to North Water Diversion Zhanggu section Yongnian county （pile No.74＋660-75＋095） segments found collapsible in loess foundation after the completion of embankment, the traditional treatment （as dynamic compaction and overturning） method has bad impact on the construction time and affect the nearby villagers and housing. The soil compaction pile method can improve the soil physical properties effectively and eliminate the collapsibility of the loess foundation, at the same time, construction equipment is simple that saves a large work amount of excavation and backfilling, save construction investment and shorten the construction period.
