摘要

为了研究带帽刚性桩复合地基荷载传递机理，基于弹性理论和合理假定，采用荷载传递函数法，建立了带帽刚性桩复合地基中桩体沉降及其轴向应力、桩帽下土体竖向位移及其竖向应力、桩帽间土体竖向位移及其竖向应力、桩身侧摩阻力、桩帽边缘土体之间的侧摩阻力与荷载水平、深度之间的控制微分方程。采用微分方程的近似解法，推导出相应地解析表达式。利用桩体荷载沉降关系作为已知条件进行求解，计算结果能够反映带帽刚性桩复合地基荷载传递的一般力学性状规律。

Abstract

Based on elastic theory and reasonable assumption

the control differential equations have been put forward by adopting the load-transfer function method in order to research the load transfer mechanism of composite foundation of rigid piles with cap

including relations among pile settlement and its axial stress

vertical displacement of soil under pile cap and vertical stress of it

vertical displacement of soil besides pile cap and vertical stress of it

the friction force of pile-side

the soil friction force of the edge of pile cap and load level

depth in rigid pile with cap composite foundation. The corresponding analytical formulas have also been derived by using approximate solution method of differential equation. The calculation results can image basically the mechanical behavior rules of the load transfer for rigid pile with cap composite foundation according to the method proposed

using directly the relation of load-settlement of pile tests as known condition.
