A Joint Shear Test for Reinforcement by Cablebolting

Abstract

In jointed rockmass, it is important to understand the effect of reinforcement of shearing joint by cablebolting. We tried to performed laboratory shear test under the several conditions like strength of rock, characterization of joint roughness and some kind of bolts. The experimental results indicate that the reinforcement by cablebolt give effects of confining the joint almost equally in comparison with PS anchor method.
In addition, we tried to evaluate the result of laboratory shear test by numerical analysis using shear joint model we suggested from the data of these test.
