Numerical Research on the Load and Settlement of Single Pile in Layered Soil Using Load Transmission Method

根据Hedinger和O’Neill提出的荷载传递函数对单桩进行了分析,对该传递函数的参数取值作了探讨,采用矩阵位移法计算桩结构的内力与节点位移,编制了计算程序,与一个工程实例作了比较,证明本文方法是可行的.在此基础上,计算了侧摩阻力、轴力的分布形式.

The characteristics of single pile in layered soil are analyzed using load transmission method based on the load transmission function by Heydinger and O＇Neill. The parameter values of the transfer function are discussed. Matrix displacement method is used to calculate the internal force of pile structure and node displacement. A calculation program is prepared. Comparison is made with an engineering example,and the result is in good conformity. At the same time, the form of the frictional resistance and the axial force is also calculated.
