| 摘 要： | 基于弹性理论和假定荷载传递函数形式。对带帽单桩桩土相互作用进行线性分析。根据文献的思路和方法。推导出沉降、竖向应力、侧摩阻力等与荷载水平、深度之间的控制微分方程。采用微分方程的近似解法，得到了相应的解析表达式。直接利用试桩成果的桩顶荷载沉降笑系作为已知条件进行求解，所得结果能够反映带帽单桩桩土相互作用力学性状的一般规律。

| Abstract: | Based on elastic theory and assumed load- transfer function, the differential equations between load- settlement, vertical stress, friction force of pile- side and depth have been derived. The corresponding analytical formulas have also been derived by using approximate solution method - district method of differential equation. The ealeulation results can image basically the mechanics character rules of the interaction between pile and soil for single pile with cap aeeording to the method of the paper, using directly the relation of load - settlement of pile tests as the known condition. |
