| 摘 要： | 在对传统剪滞模型基本原理及受力特点进行分析的基础上，提出一种改进的剪滞模型，并利用该模型对预应力岩石锚杆作用机理进行分析，得到了浆体材料与岩体间的剪应力、钢筋与浆体材料间的结合应力分布模式及荷载-位移特性；并对该模型进行了受力分析，得到一些有实际意义的结论。

| Abstract: | A refined shear lag model is presented based on the analysis on the basic principle and mechanical characteristic of traditional shear lag model. The model is applied to the analysis on mechanism of pre-stress anchor bolt, shear stress between grouting material and rock and bond stress distribution model & loading-deformation characteristic were obtained. Stress analysis was also made on the model for some conclusions with practical significance. |
