Analysis of Stress Distribution Model Along Anchoring Section of Prestressed Rock Bolt

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.
