Numerical Simulation of Stress Arching Effect in Horizontally Layered Jointed Rock Mass [PDF]
Symmetry, 2021 Stress arching effect during the excavation of broken surrounding rock in underground engineering has an important influence on the stability of surrounding rock after underground excavation. To determine the stress arching effect in horizontally layered jointed rock mass, the stress arching characteristics of surrounding rock mass after excavation is ...

Mass-Radius Relations and Core-Envelope Decompositions of Super-Earths and Sub-Neptunes
, 2014 Many exoplanets have been discovered with radii of 1-4 Earth radii, between that of Earth and Neptune. A number of these are known to have densities consistent with solid compositions, while others are "sub-Neptunes" likely to have significant hydrogen ...

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 ...
