摘要
通过对广州—佛山高速公路扩建工程及北京—珠海高速公路软土地基处理工程的研究，分析了粉喷桩、土应力转化及相互作用，进而对桩的轴向应力、复合地基沉降、作用机理进行了研究，并提出了用粉喷桩复合地基加固软土地基的几点看法。
The stress distribution,stress transformation and the interaction between the soil and the piles are analyzed in this paper,based on the extension engineering of express way from Guangzhou to Foshan and the express way from Beijing to Zhuhai. Further more,the settlement and act mechanism of the com-posite foundation are researched,the method to calculate the composite foundation capacity is advised too.
