| 摘 要： | 基于弹性桩的挠曲微分方程,结合Winkler地基模型和Poulos两阶段法,提出了一种近似考虑土体侧移和既有轴向荷载耦合作用的单桩简化算法,采用有限差分方法进行求解,求解过程简便并可应用于分层地基中.通过与典型算例的对比,验证了该方法的合理性.参数分析表明,在土体侧移与轴向荷载耦合作用下,由于P-△效应,将在桩身内产生...

| Abstract: | Based on the flexural differential equation of elastic piles,a simplified analytical solution of an axially loaded single pile subjected to lateral soil movement is put forward.In this solution,the subsoil is simulated with the Winkler's spring model and a two-stage method proposed by Poulos is introduced to establish the equations.The flexural differential equation is solved by the finite difference method,which is more convenient and more adaptable for layered foundations.The method is validated by some t... |
