| 摘 要： | 本文系统总结了锚杆轴力分布型式,分析了各轴力分布型式的力学机理。结果表明,在围岩不同区内,锚杆所受剪切力具有不同的特点,而且,锚杆所受剪切的特点在锚杆轴力分布中得到了反映。根据以上关系,提出了利用锚杆轴力量测确定围岩破坏区的方法。

| Abstract: | This paper summarizes the modes of axial stress distribution of bolt and analyses their mechanism.It is shown that the characteristics of shear stress acting on bolt vary in different zones zone of surrounding rock and are reflected in the axial stress distribution of bolt.Based on this relation,this paper suggests a method for defermining failure zone of surrounding rock by means of axial stress measurement of bolt. |
