摘要

假定抗浮锚杆各部分贡献的位移与锚杆轴力均呈线弹性关系，运用力学原理分析锚杆轴力与锚侧摩阻力、锚-土变形之间的相互关系，推导出锚杆的摩阻力、轴力及各部分变形与锚杆各参数的相互关系。实例验证结果表明：基于线弹性模型基础上建立的摩阻力、轴力和位移公式能够较好地描述垂向抗浮锚杆在弹性变形阶段的内力和变形形态；获得了抗浮锚杆摩阻力和剪切位移沿锚固长度的分布规律；证实了锚土界面处变形为土层抗浮锚杆变形的主要部分。

Abstract

On the assumption that any part of displacement of anti-float anchor is linear elastic relation

the relations about frictional resistance

axial force and displacement between soil and bolt can be derived by applying the mechanics theory. The example shows that based on the linear elastic analysis model

the formulas of frictional resistance

axial force and displacement can describe the elastic stress and strain better. The distribution of frictional resistance and shear displacement along the anti- float anchoring length are obtained. It comfirms that the shear displacement between the bolt and surrounding soil is main displacement for the bolts buried in soil.
