摘要
本文利用数值分析方法,对层状地基中大直径超长群桩的荷载位移曲线、桩侧摩阻力及桩端阻力、桩顶反力、桩身轴力的分布规律等进行了较为系统地研究,同时对比分析了层状地基中土体本构模型的选择对数值分析结果的影响,所得结果对深入研究该类桩基的承载及变形特性具有一定的参考价值.
According to the actual geological data of a project, the load displacement curve, the pile side friction resistance, the pile top reaction force, the pile axial force and the pile foundation force of the large diameter long group pile in the layered foundation are studied by using the large nonlinear finite element analysis software ABAQUS. The influence of the constitutive model of the soil in the layered soil on the numerical analysis results is analyzed, and the corresponding reference is put forward for the numerical simulation and design of the pile group.
