Reinforcing effects of bolting in jointed rock mass

A rock bolt is one of 3 major support members, including shotcrete, steel rib, playing an important role in stabilizing the underground space with its various functions. Currently, studies at home and abroad tend to focus on the development of new rock bolt methods. For most of the studies on the re...

description A rock bolt is one of 3 major support members, including shotcrete, steel rib, playing an important role in stabilizing the underground space with its various functions. Currently, studies at home and abroad tend to focus on the development of new rock bolt methods. For most of the studies on the reinforcing effects, a numerical analysis has been adopted; however the experimental analysis is insufficient. Therefore this study tried to create a model ground of the jointed rock mass in a cantilever shape and to carry out a large scale model test. Subsequently, it sought to inversely derive the modulus of the elasticity of the model ground with a deflection formula of the cantilever and proposed the reinforcing effects of the rock bolt using the equation.
