摘要

为了从荷载传递微分方程导出具有实际意义的非线性解析解，建立一种简单的沿桩长轴力分布函数和位移分布函数之间的关系模型U(z)-?(z)是非常重要的。采用建立经验公式类数学模型的方法，从几何作图法获得的U(z)-?(z)曲线的形状入手，通过对若干个数学模型的试算，确定了指数形式的模型，并对模型中的参数意义和确定进行了讨论，认为参数?，b只与桩顶和桩底位移有关。

Abstract

To get useful no-linear analytical resolutions from load-transfer differential equation

it is very important to establish a relationship model between axial force distribution function and displacement distribution function

i.e. U(z)-?(z). In this paper

the exponential model is selected by means of the method setting up experience formula

the shapes of curves of U(z)-?(z) gained by geometric construction method and the tentative calculations to many other models. The meanings and determining of the parameters in the model are discussed. The results show that the parameters ?

b only has a connection with the displacements of top and bottom on uplift pile.
