［摘要］通過某工程案例對水泥土擠密樁和素土擠密樁+CFG樁復(fù)合地基兩種地基處理方案從地基承載力、變形、工期、造價等方面進(jìn)行比較，并遵循技術(shù)可靠、經(jīng)濟(jì)合理、施工便利的原則，最終確定采用水泥土擠密樁地基處理方案。對地基處理效果的檢測表明，該方案達(dá)到了設(shè)計要求，節(jié)約了成本，縮短了工期，在同類地質(zhì)條件的小高層、高層建筑中可以推廣應(yīng)用。

Abstract:Composite foundation of compacted soil-cement pile and soil-CFG pile were compared based on a project from the comparison of bearing capacity, subsoil deformation, construction period and costs. According to the principles including reliable technology, reasonable economy and construction convenient, compacted soil-cement pile was adopted finally. The test results of the composite foundation show that the scheme meet the design requirements，save the cost and shortened construction period. It can be widely applied in the tall building construction under the same geological conditions.
Keywords:compacted soil-cement pile; soil-CFG pile; collapsible loess; tall building
