Paper Number: ISRM-SINOROCK-2013-040
...-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...
