摘　　要：采用挤密成孔夯实水泥土桩复合地基处理湿陷性地基,可以有效地提高地基承载力同时消除地基的湿陷性。但对于地基局部含水量过大时,会造成沉降量偏大,处理效果不明显,同时施工过程会出现缩孔现象。采用石灰桩吸水与水泥土桩组合应用的方法,可有效控制地基不均匀沉降,取得了良好的效果。It can eliminate the collapsibility of the foundation and improve the bearing capacity that adopts the tamping soil-cement pile through squeezing to form pore.But too much the moisture content of the local foundation sometimes is easy to cause too many the settling volume of the foundation;it isn't obvious effect to prevent the foundation from settling.Utilizing the lime pile to absorb the water in the foundation and combining it with the soil-cement pile can effectually decrease the uneven subsidence of the foundation.
