广义荷载传递函数及其应用

单桩非线性分析的方法很多，荷载传递函数法是其中很重要的一种。鉴于问题的复杂性，该方法中的荷载传递函数存在多种形式，且都具有各自适用的范围，存在局限性。广义荷载传递函数是一个通用函数式，其通过增加一个参数实现变换函数形式的目的，使之能够反映以前所提的各种荷载传递函数。另外，还可以描述目前没有提出、但可能存在的荷载传递函数形式，具有广泛适用性；同时，在某种程度上能反映软化效应。在工程应用中取得场地土性参数的前提下，适当运用该函数可以减少试桩的数量，产生巨大的经济价值。

Generalized load transfer function and its application

There are lots of nonlinear analysis methods on studying piles. Among these methods, the load transfer function method is an important one. And the complexity of problem results in many function forms that can be used in some range. The generalized load transfer function is a universal function form that can reflect all functions reported in the literature. The generalized load transfer function can be transformed to other forms by adding a parameter. At the same time, it can reflect the softening effect. Based on realizing the mechanics parameters of soil in site, the adoption of this function can decrease number of trial piles. Therefore, it can make the project to be more economic.
