摘要
建立了变刚度刚性桩复合地基的桩-土体系近似分析模型,并采用无单元法模拟筏板,有限元方法模拟褥垫层,将三者耦合建立了刚性桩复合地基筏板基础的一种计算方法.根据大比尺模型实验的结果,对该方法的合理性和可行性进行了论证.
A set of approximate analysis formulas of pile-soil system in rigid pile composite foundations is derived. The element-free method is used to simulate the raft on the composite foundations, and the finite element method to solve the cushion. A computation method of raft foundation on variable stiffness rigid pile composite foundations is established by coupled the pile-soil system and the cushion as well as the raft, based on the displacement continuity. The reasonability and reliability of the proposed method are showed by the results of a large-scale model experiment.
