Open AccessExperimental verification of the intrinsic strainburst proneness of various rock types
A portion of excess strain energy is converted into kinetic energy after the peak load in Class II rock. That is the intrinsic potential energy for strainburst. Therefore, the intrinsic strainburst proneness o...

Effect of lateral stress on shear strength of jointed hard rocks in true triaxial single-shear test
Shear failure along joints is one of the typical failure modes in deep underground rock masses, and indoor direct shear tests are commonly used to study the shear mechanical behavior of joints. However, deep u...
