An Index for Estimating the Stability of the Layered Rock Masses under Excavation Disturbance
Advances in Materials Science and Engineering, 2018 The mechanical behaviours of layered rock mass exhibit significant differences in the directions parallel and vertical to the bedding planes. The deformation and failure of a layered rock mass has remarkable weak-plane dependence, which brings a major ...
