Abstract In current research, a novel geometrical technique is introduced to estimate the length ( L ) of sliding arc by considering slip surface entry point distance d e ). Morgenstern-Price limiting equilibrium and strength reduction methods are selected within framework SLOPE/W FLAC 3D softwares respectively, study mechanism stability-effecting factor for loose rock slope comprise two differ...

The problem of roadway support in swelling soft rock was one of the challenging problems during mining. For most geological conditions, combinations of two or more supporting approaches could meet the requirements of most roadways; however, in extremely swelling soft rock, combined approaches even could not control large deformations. The purpose of this work was to probe the roadway deformatio...
