CFG桩可较大幅度地提高天然地基的承载力,降低建筑物的基础沉降,并且具有施工方法简单易行、适用地层范围广泛、施工周期短、造价低和污染小等优点,近年来,在全国各个地区得到了广泛的应用。本文分析了CFG桩提高地基承载力的机理,举例介绍了CFG桩复合地基在某工程中的应用情况,指出施工中应注意的问题,期望着CFG桩复合地基技术能更趋成熟,能够得到更加熟练得应用。
CFG piles can greatly increase the bearing capacity of natural foundations, reduce the foundation settlement of buildings, and have the advantages of simple and easy construction methods, wide range of applicable strata, short construction period, low cost, and low pollution. In recent years, Various areas throughout the country have been widely used. This paper analyzes the mechanism of CFG piles to improve the bearing capacity of the foundation. It also gives an example of the application of CFG pile composite foundation in a project and points out the problems that should be paid attention to during construction. It is expected that the CFG pile composite foundation technology will become more mature and can be further improved. Skilled application.
