摘　　要：采用有限元方法,对带帽刚性桩复合地基力学性状进行了初步的数值模拟分析,找出了带帽刚性桩复合地基力学性状的一些基本规律。带帽刚性桩复合地基在一定深度位置处存在等沉面现象,为建立带帽桩复合地基沉降计算模型提供了理论依据,并为设计提供有益指导。The mechanical characters of composite foundation with capped rigid piles have been analyzed by means of finite element method （FEM）. The change rules of the mechanical characters of the composite foundation have been researched. The equal settlement section of rigid pile with cap composite foundation has been proved. The results provides a theoretical base for the establishment of a calculation model for the composite foundation settlement, and a useful guidance for the engineering construction and design.
