摘要
文章从锚杆剪应力—剪切位移本构模型出发,得出了锚杆处于弹性阶段、塑性阶段和残余强度阶段的剪应力表达式;并以此为基础,研究了三个阶段的剪应力分布规律,阐述了锚杆载荷传递特性,为锚杆锚固机理的研究和锚杆锚固状态的监测提供理论基础。
From the constitutive model of the bolt shear stress-shear displacement,the shear stress expressions at the bolt at the elastic stage,plastic stage and residual strength stage were obtained.Base on the circumstances,the stress distribution law of the three stages was studied and the load transmission features of the bolt were stated.All those could provide the theoretical basis to the study of the bolt anchoring mechanism and monitoring and measuring of the bolt anchoring status.
