摘要

为了较准确地计算横向荷载作用下桩-土耦合系统的土弹簧刚度

首先基于Mindlin公式得到了力与变形量之间的关系

导出了土弹簧刚度与深度以及土体参数之间的关系.由于公式较复杂

故采用Matlab软件编制程序

计算了各弹簧单元的刚度系数

最后使用ANSYS软件计算了在此弹簧刚度系数下桩的变形及各弹簧的压力.通过与常用的基于Boussinesq解导出弹簧刚度的计算结果比较

两种方法所求出的桩体位移吻合较好.结果表明:采用Mindlin导出的位移解能更准确地确定土弹簧刚度系数.

Abstract

In order to accurately calculate the stiffness of soil spring for pile-soil coupling system under transverse load

the relation between force and displacement was firstly obtained by using Mindlin′s formula and the relation between the stiffness of soil spring and depth as well as parameters of soil was derived.Because of the complexity of the formula

a program of Matlab software which can display spring stiffness was worked out directly.At last

the deformation of pile and the pressures on all soil springs were calculated with ANSYS.By comparing with the results based on Boussinesq′s solution

the displacements of plies calculated by two methods are relatively coincident.The results show that the stiffness coefficients of soil spring can be accurately determined by using Mindlin′s formula.
