Journal ArticleDOI
Experimental study of the hydro-mechanical behavior of rock joints using a parallel-plate model containing contact areas and artificial fractures
TL;DR: In this article, a new shear-flow testing apparatus with specially designed fluid sealing techniques for rock fractures were developed, under constant normal load (CNL) or constant normal stiffness (CNS) constraint.
Journal ArticleDOI
Estimating the relation between surface roughness and mechanical properties of rock joints
TL;DR: In this paper, a 3D laser scanning profilometer system was used to measure the surface roughness of a single rock joint under both constant normal load (CNL) and constant normal stiffness (CNS) conditions and measured the surfaces of rock joints before and after shearing.
Journal ArticleDOI
A fractal model for characterizing fluid flow in fractured rock masses based on randomly distributed rock fracture networks
TL;DR: In this paper, a fractal model that represents the geometric characteristics of rock fracture networks is proposed to link the fractal characteristics with the equivalent permeability of the fracture networks, which is shown to be significantly influenced by the tortuosity of the fluid flow and the aperture of the fractures.
Journal ArticleDOI
Experimental and numerical study of the geometrical and hydraulic characteristics of a single rock fracture during shear
TL;DR: In this paper, a mathematical equation is proposed to describe the relation between hydraulic aperture and mechanical aperture by means of the ratio of the standard deviation of local mechanical aperture to its mean value.
Journal ArticleDOI
An analytical model to predict axial load in grouted rock bolt for soft rock tunnelling
TL;DR: In this article, an analytical model is proposed to predict the axial force of grouted rock bolt in the tunnelling design, and the interaction mechanism of the rock bolt and the soft rock mass has been described according to their consistent displacement.
