TL;DR: In this article, a new theory and testing method for deep underground rock mass under coupled static-dynamic loading are introduced, and the results of true triaxial unloading compression tests on granite and red sandstone indicate that the unloading can induce slabbing when the confining pressure exceeds a certain threshold and the slabbing failure strength is lower than the shear failure strength according to the conventional MohrColumn criterion.

TL;DR: A series of rock tests including Brazilian indirect tension test (BITT), three-point bending test (TPBT), modified shear test (MST), and uniaxial compression test (UCT) were conducted to investigate the acoustic emission (AE) characteristics and crack classification during rock fracture.

TL;DR: In this paper, the failure behaviors of different rock types (granite, red sandstone, and cement mortar) were investigated using a novel testing system coupled to true-triaxial static loads and local dynamic disturbances.

TL;DR: In this article, the uniaxial compressive strength and rockburst tendency of red sandstone are measured and the mechanism by which spalling damage on induces rockburst is revealed.

TL;DR: In this article, a binary linear regression model was proposed to determine the thickness variation of the excavation damage zone (EDZ) correlated with the excavation span and a coupled index of rock properties and buried depth of opening.
