摘要

推导了砂土地基中闭口管桩的沉桩影响半径以及刚性桩的横向承载力（矩）。通过使用MATLAB程序对单桩轴向刚度的分析，得出了其与桩周单位深度土的等效刚度系数、桩端土的等效刚度系数、钢管桩的壁厚、桩径、桩长、桩身弹性模量等参数之间的一些关系，从而为此类桩的优化设计提供了理论依据。在此基础上通过桩身荷载传递的双曲线函数模型以及相关参数，在已知（假定）桩身压缩量的情况下求出相应的桩顶轴力。

Abstract

This paper has deduced the effected diameter of a closed large diameter pipe pile on sand ground as well as the horizontal resistance (or moment) acting on the rigid large diameter pipe pile. And

it provides the theoretically optimal design for the similar case; and by using the MATLAB program to analyze the axial stiffness of single pile

the relationships of stiffness of single pile

and the equivalent stiffness modulus of the soil beside the pile for unit depth

the equivalent stiffness modulus of the soil at the bottom of the pile

the thickness of the steel pipe pile

as well as its diameter

length and the elastic modulus for the used material are now much more clear. Based on this idea

the corresponding axial force can be calculated by using the load transfer hyperbolic function for known or assumed compressive deformation of the pile body.
