Journal ArticleDOI
Scale effect on the shear behaviour of rock joints based on a numerical study
TL;DR: In this paper, the effect of joint length on the shear behavior of rough rock joints using PFC2D was investigated and it was found that the mobilisation of different sized asperities at different scales resulted in the observed scale effect.
Journal ArticleDOI
Experimental and numerical study of asperity degradation in the direct shear test
TL;DR: In this article, the authors used PFC2D to simulate the shear behavior and mechanisms of asperity degradation of rock joints under direct shear tests using numerical and experimental approaches.
Journal ArticleDOI
Parametric Study of Smooth Joint Parameters on the Shear Behaviour of Rock Joints
TL;DR: In this paper, the particle flow code PFC2D was used to simulate the shear behavior of smooth joints in a direct shear test using the modified smooth joint (SJ) model.
Journal ArticleDOI

TL;DR: The CERCHAR Abrasivity Test (CAI) was originally developed by the Laboratoire du Centre d'Etudes et Recherches des Charbonnages (CERCHAR) de France for coal mining applications as discussed by the authors.
Journal ArticleDOI
The effects of water content, temperature and loading rate on strength and failure process of frozen rocks
TL;DR: In this paper, the effects of water content, temperature and loading rate on the strength and failure process of rock at sub-zero temperatures were investigated and the results showed that the presence of water in the rock resulted in a marked increase in rock strength and fracture initiation stress.
