| 中文摘要 | 通过将反映桩基荷载传递机理的“套叠”式桩周土变形模式与弹性理论相结合,推导了桩身带有承力盘DX抗拔桩的荷载-位移关系的解析解。该解析解可反映桩的变形以及桩周土模量随深度变化等因素的影响,且计算较为简便。通过有限元数值模拟对计算模式可能引起的误差进行分析并以DX抗拔桩现场试验结果进行了验证,表明给出的解析解可较好地反映DX抗拔桩在工作状态下的荷载-位移关系,可为DX抗拔桩的工程设计提供参考。; Based on the elastic theory and the overlapped-form strain mode of the soil surrounding a pile,an analytical solution for the load-displacement relationship of cast-in-situ DX pile is presented.The proposed solution can reflect the influence of the deformation of pile and non-homogeneity of soils′ modulus along the depth in load-displacement relationship.The comparison with FEM analysis and full-scale test results showed that the analytical solution can well predict the displacement of pullout DX pile.The solution is simple and convenient,and can be used as a practical reference to the design of pullout DX pile. |
