摘　　要：工程中应用碎石桩加固地基已有84年历史,主要应用于加固处理黏性土、粉土、砂土、湿陷性黄土、盐渍土等特殊土地基。工程实践表明,碎石桩复合地基的破坏主要是承载力不足与沉降变形。本文针对碎石桩复合地基承载力理论与变形计算方法进行总结,归纳分析了碎石桩复合地基承载力计算方法,运用有限元软件进行数值模拟分析的方法。Gravel pile has been used to reinforce foundation for 84 years. It is mainly used to reinforce clay, silt, sand, collapsible loess, saline soil and other special soil foundations. Engineering practice shows that the failure of gravel pile composite foundation is mainly caused by insufficient bearing capacity and settlement deformation. This paper summarizes the bearing capacity theory and deformation calculation method of gravel pile composite foundation, summarizes and analyzes the bearing capacity calculation method of gravel pile composite foundation, and uses finite element software to carry out numerical simulation analysis method.
