Three-dimensional numerical analysis for rock slope stability using shear strength reduction method
TL;DR: In this article, a numerical modeling of 3D slopes is performed using the shear strength reduction (SSR) technique based on the linear Mohr-Coulomb (MC) criterion.
Journal ArticleDOI
Terrestrial remote sensing-based estimation of mean trace length, trace intensity and block size/shape
TL;DR: In this article, the authors investigated the potential of terrestrial remote sensing techniques for the estimation of mean trace length, trace intensity and block size/shape, and compared with field-based scanline measurements.

Breaking processes in three-dimensional bonded granular materials with general shapes
TL;DR: An extension to the spheropolyhedra method for the simulation of granular materials comprising particles of general shapes with bonding, cement, or cohesion model for particles sharing common faces is introduced and it is found that the peak strength envelope is the product of the superposition of frictional and fracture failure mechanisms.

Composite rock slope kinematics at the current Randa instability, Switzerland, based on remote sensing and numerical modeling
TL;DR: In this paper, LiDAR and GB-DInSAR data were combined with 3D geodetic measurements to characterize the rock mass structure and displacement patterns of the Randa rock slope instability in southern Switzerland.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

Underground excavations in rock
Evert Hoek,Edwin T. Brown +1 more
TL;DR: In this article, the geotechnical aspects of the design of underground openings for mining and civil engineering purposes are discussed, and a number of worked examples to assist the reader in applying the techniques described to his or her own problems.
Hoek-brown failure criterion - 2002 edition
TL;DR: The Hoek-Brown failure criterion for rock masses is widely accepted and has been applied in a large number of projects around the world as discussed by the authors, however, there are some uncertainties and inaccuracies that have made the criterion inconvenient to apply and to incorporate into numerical models and limit equilibrium programs.

Journal ArticleDOI
Strength of jointed rock masses
TL;DR: In this paper, a simple empirical failure criterion is presented and its application in engineering design is illustrated by means of a number of practical examples, and the authors summarize some of the basic information upon which such simplifying assumptions can be made.
