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.

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.

Empirical estimation of rock mass modulus
Evert Hoek,Mark S. Diederichs +1 more
TL;DR: In this article, a sigmoid function based relationship was proposed for estimating the value of rock mass deformation modulus on the basis of classification schemes and the properties of intact rock as well as the effects of disturbance due to blast damage and/or stress relaxation are also included in this new relationship.

A clumped particle model for rock
N. Cho,C.D. Martin,D.C. Sego +2 more
TL;DR: In this article, an extensive series of calibrations were carried out using a particle code to determine if the micro-parameters determined from uniaxial compression tests could be used to predict the intact rock response regardless of stress path, i.e., tension to triaxial compression.

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.
Book
Engineering rock mass classifications
TL;DR: The Caracterisation Reference Record (CR) was created on 2004-09-07, modified on 2016-08-08 as discussed by the authors, and was used for classification of classification labels.

The progressive fracture of Lac du Bonnet granite
C.D. Martin,N.A. Chandler +1 more
TL;DR: The strength of intact rock is made up of two components: the intrinsic strength, or cohesion; and the frictional strength as discussed by the authors, and it is generally assumed that cohesion and friction are mobilized at the same displacements such that both components can be relied on simultaneously.

Support of underground excavations in hard rock
TL;DR: In this paper, a reference record was created on 2004-09-07, modified on 2016-08-08 and used for the purpose of Dimensionnement Classification and Excavation.
