摘　　要：分析了带帽刚性疏桩复合地基的思路形成过程、设计思想、变形机理及其形成复合地基的条件，在现场试验的基础上，提出了带帽刚性疏桩复合地基计算模型，并提出了相应的三种沉降计算模式，为带帽刚性疏桩复合地基作用机理理论研究提供基础。The process of forming, the thought of designing, the deformation mechanism and the forming condition of composite foundation have been analyzed for rigid and sparse piles with cap composite foundation. The calculation model of it has been put forward on the base of the spot test, the three corresponding modes of settlement calculation have also been bring forward. These can provide the useful guidance for the engineering construction, design and theory research of the working mechanism for the rigid and sparse piles with cap composite foundation.
