A review of techniques, advances and outstanding issues in numerical modelling for rock mechanics and rock engineering
TL;DR: In this paper, the authors present the techniques, advances, problems and likely future developments in numerical modelling for rock mechanics and discuss the value that is obtained from the modelling, especially the enhanced understanding of those mechanisms initiated by engineering perturbations.
Experimental studies of scale effects on the shear behaviour of rock joints
TL;DR: In this paper, the effect of scale on the shear behavior of joints is studied by performing direct shear tests on different sized replicas cast from various natural joint surfaces, and it is shown that scale effects are more pronounced in the case of rough, undulating joints, whereas they are virtually absent for planar joints.

Terrestrial laser scanning of rock slope instabilities
TL;DR: A review on the application of a remote sensing technique (terrestrial laser scanning, TLS) to a well-known topic (rock slope characterization and monitoring) is presented in this article.
Journal ArticleDOI
Geotechnical and operational applications for 3-dimensional laser scanning in drill and blast tunnels
TL;DR: In this paper, a 3D laser scanning (Lidar) system is used to estimate shotcrete thickness, as-built bolt spacing, and regions of potential leakage in underground tunnels.
Journal ArticleDOI
Roughness decomposition and nonlinear fluid flow in a single rock fracture
TL;DR: In this article, the effects of wall surface roughness on fluid flow through rock fractures were investigated using a wavelet analysis technique to define a mathematical criteri cercle for the problem.

How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension
TL;DR: Geographical curves are so involved in their detail that their lengths are often infinite or, rather, undefinable; however, many are statistically "selfsimilar," meaning that each portion can be considered a reduced-scale image of the whole.
Journal ArticleDOI
The shear strength of rock joints in theory and practice
Nick Barton,V. Choubey +1 more
TL;DR: In this paper, the authors describe an empirical law of friction for rock joints, which can be used both for extrapolating and predicting shear strength data, and demonstrate that it can be estimated to within ± 1° for any one of the eight rock types investigated.
Journal ArticleDOI
Review of a new shear-strength criterion for rock joints
TL;DR: In this paper, a sliding scale of roughness is proposed for estimating the shear strength of rough joints, and the curvature of the proposed strength envelopes reduces as the roughness coefficient reduces, and also varies with the strength of the weathered joint wall or unweathered rock.
Journal ArticleDOI
Self-Affine Fractals and Fractal Dimension
TL;DR: In this article, it was shown that the global fractal dimension of a self-affine fractal curve can be computed by walking a compass along the fractal path of a scalar Bownian record.

Broad bandwidth study of the topography of natural rock surfaces
TL;DR: In this article, the authors studied the topography of various natural rock surfaces from wavelengths less than 20 microns to nearly 1 meter, including fresh natural joints (mode I cracks) in both crystalline and sedimentary rocks, a frictional wear surface formed by glaciation and a bedding plane surface.
