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.
