... laboratory experiments for exploring such coupling are very limited (Ye and Ghassemi, 2018; Ishibashi et al., 2018). This study presents the experimental results those explore the linkage between mechanical and hydraulic properties of the fractured rock of granite during hydraulic shearing under high stress...

Rock samples from a geological section spanning ~150 m were powdered for friction experiments at recreated in-situ stresses and temperatures. Experimental results show that fault frictional and stability...
