摘　　要：粉喷桩是处理软弱地基的一种重要形式。从水泥加固土和桩的承载作用两个方面分析了粉喷桩的工作机理,并从桩土的应力和变形特征出发,研究了粉喷桩复合地基的承载特性。Dry jet mixing pile is an important method to treat weak foundation. The author mechanism of dry jet mixing pile from cement reinforcing soil and pile load beating characteristics, the interaction between pile and soil in the composite foundation was analyzed the working ~ From stress and strain studied~ The paper can provide theoretical guidance to the engineering design and construction.
