摘要： 荷载传递法广泛用于桩基沉降的计算中，其关键在于荷载传递函数的选择及相关参数的确定，国内外学者就其函数的选择和参数的确定做了大量的研究和试验，证明双曲线函数能更好的模拟桩土间非线性的关系，就桩侧荷载传递模型的研究发展及计算步骤做了综述，总结了土在不同的本构关系下，桩侧荷载函数的表示方法，同时，充分利用位移协调条件，采用迭代算法计算桩身沉降和桩侧阻力。

Abstract: Load transfer function method is widely used in the settlement prediction of pile foundations. It is a simple and practical method first proposed by Seed and Reese in 1957. The key aspects in the pile settlement prediction are to select an appropriate function and determine the parameters. A large quantity of research and testing are available.  It is suggested that the hyperbolic functions can better fit the nonlinear relationship between the pile and the surrounding soil. This article reviews the development of the shaft load transfer functions and its applications. The different expressions of the load transfer function under various constitutive models. The pile settlement is obtained through iterations by considering the deformation compatibility.
