某CM复合地基的长螺旋桩质量处理

Quality Treatment of Long Screw Pile for a CM Composite Foundation

CM复合地基具有布置合理,刚性桩与亚刚性桩的平面交叉布置和空间长短布置使平面及空间形成刚度梯度,从而获得了高强度的复合地基的优点。该复合地基在基础施工和应用还处在起步阶段,还有很多质量防控经验需要我们在实践中不断积累。

CM composite foundation is reasonable in layout because the rigid piles( C pile) and semi-rigid piles are cross laid out in plane and are laid out with different length in space,which forms rigid gradient to attain high strength composite foundation. Because this composite foundation is used preliminary in practice engineering,so some quality control experience is accumulated from practice.
