The results show that two pump...

... ABSTRACT Minor joints exist ubiquitously in deep-buried brittle rock masses subjected to high in-situ stress. These joints affect the strength and deformation properties and lead to the concentration and dissipation of stress wave propagation. Through modeling and verification, the rock mass...
