土挤密桩与CFG桩复合地基在工程中的应用

The application of the soil intimate pile and the composition foundation of CFG pile

分析了土挤密桩与CFG桩复合地基的基本原理,结合具体工程实例,通过现场检测得出了该复合地基能使地基承载力大幅度提高的结论,指出该复合地基变形小、稳定快、施工简单易行、工程质量易保证、经济效益和社会效益非常显著,以推广该复合地基的应用。

The paper analyzes the basic principle of the soil intimate pile and the composition foundation of CFG pile. By combining the actual construction example, it concludes that the composition foundation can improve the loading capacity of the foundation in a great way by the site inspection, points out the deformation of the composition foundation is little, while its stability is fast, the ways of construction is easy, so the constmction quality can be ensured and its economic benefits and social benefits are obvious, in order to expand its application in the composition foundation.
