碎石挤密桩在软粘土地基中的应用

碎石桩用于处理软粘土地基,可起到置换和排水的作用,加速土的固结。形成的桩体与固结后软粘土的复合地基,能显著地提高地基土抗剪强度,从而提高地基土的承载力,减小地基的沉降与变形。这种桩施工机具常规,操作工艺简单,场地干净,可节省水泥、钢材,能就地使用廉价地方材料,加速进度,降低工程成本,应用较为广泛。

Replacement stone column is used to deal with soft clay foundation ,it can play the role of replacement and drainage, accelerate the consolidation of soil. The composite foundation that the pile and consolidation of after the soft clay, it can improve the shear strength of soil significantly, thereby enhanc the bearing capacity of foundation soil, reduce the foundation of the settlement and deformation. This pile of conventional equipment ,the operation process is simple, site is clean, can save cement and steel, be able to spot the use of cheap local materials, to accelerate progress and reduce the cost of the project ,so it is applied more widely.
