摘要

基于现浇X形桩在任意方向轴惯性矩控制方程和异形几何截面特性以及地基反力法的基本原理，分析X形桩在任意水平向荷载作用下截面应力分布规律及其控制参数变量对截面应力集中现象的影响规律，并与同等情况下等周长和等面积的圆形桩、方形桩的力学特性进行对比分析，提出考虑截面应力分布的X形截面设计最优化设计形式，为X形桩截面形式设计提供参考依据。研究结果表明，等面积情况下，X形桩截面的应力随着外包圆直径的增大而减小，随着开弧间距和开弧角度的减小而减小；等周长情况下，X形桩截面的应力随着外包圆直径的增大而减小，随着开弧间距和开弧角度的减小而减小。实际工程中建议外包圆直径可以取0.5～0.7 m左右，开弧间距取0.1～0.2 m左右，开弧角度采用110o～130o左右。

Abstract

Base on the moment of inertia equation and sectional parameters

the X-section cast-in-place concrete pile (referred as to XCC pile) stress distribution and stress concentration equations under different directions lateral load were built; and influenced factor

such as

sectional parameters were analyzed. In order to comparatively analyze

the characteristics of circular piles and square pile with the same concrete amount or the same perimeters were carried out. Finally

one of optimized X-section type was proposed

which can be used for XCC pile design reference. The results show that

the maximum stress distribution increased with the decreasing of outsourcing diameter

the decreasing of open arc angle

and the increasing of open space with the same area. The maximum stress distribution increased with the decreasing of outsourcing diameter

the increasing of open arc angle

and the increasing of open space with the same perimeter. In this paper

0.5-0.7 m outsourcing diameter

0.1-0.2 m open space

and 110o-130o open arc angle can be chosen for recommended section parameters.
