| 摘 要： | 提出一种适用于支桩沉降分析的非线性组合算法。基于荷载传递法,对桩侧摩阻力计算采用三折线模型,对桩端阻力采用双曲线模型,提出符合支部结构力学构造的支端阻力与位移的非线性表达。为验证支桩沉降的组合计算方式,建立了模型试验,试验数据与计算数据较为吻合,具有较好的适用性及操作性。

| Abstract: | A nonlinear combination algorithm for settlement analysis of pile is proposed. Based on the load transfer method and the characteristics of pile lateral friction, the load transfer function of the three-fold line model is adopted. At the same time, according to the characteristics of pile tip resistance and branch end resistance, using the load transfer function of the hyperbolic model, the nonlinear expression of branch end resistance and displacement in conformity with the mechanical structure of the branch structure is proposed. It has good applicability and operability to set up the combined calculation method of pile settlement. |
