...-term shear strength of fractured rocks is mainly composed by two mechanisms: one is the anti-shear due to the interlocking of microasperities, the other is the anti-friction owing to the relative shear of macro waves on the fractured rock surfaces. The study concludes that the relationship between...

For investigation of mechanical characteristics of rock salt under injection and withdrawal cycles, triaxial cyclic loading tests were conducted using a MTS test system. Linear relationships between stress and strain under unloading...

... which are mainly hazards of tunneling excavation, have caused great losses in many areas of the world (Singh B. & Goel R.K., 2006). Compared to rock burst in hard rocks, it is still insufficient to understand the failure mechanism of large deformation. Large deformation in tunnels is currently very...
