<p>Although many intact rock types can be very strong, a critical confining pressure can eventually be reached in triaxial testing, such that the Mohr shear strength envelope becomes horizontal. This critical state has recently been better defined, and correct ...

The aim of this paper is the sensitivity analysis of GSI and disturbance factor dependent equations that characterize the mechanical properties of rock masses. The survey of the GSI system is not our purpose. The results show that the rock mass strength calculated ...

In this paper several case examples are presented to illustrate the application of the high-end (spalling) and low-end (weak ground) transition Hoek-Brown relationships proposed by Carter, Diederichs and Carvalho, (2007) as a basis for better defining rock ...

This paper questions the application of rock mass classification systems in engineering geology problems.

<p>In this paper the historical development of the Hoek-Brown failure criterion and the associated Geological Strength Index (GSI) has been presented.</p>

<p>This paper applies numerical limit analyses to evaluate the ultimate bearing capacity of a surface footing resting on a rock mass whose strength can be described by the generalised Hoek&ndash;Brown failure criterion [Hoek E, Carranza-Torres C, Corkum B. ...

<p>The notes are intended to provide an insight into practical rock engineering to students, geotechnical engineers and engineering geologists.</p>

<p>In this paper in order to overcome the difficulty of finding an acceptable equivalent friction angle and cohesive strength for a rock mass the program called "RocLab" is introduced, as a convenient means of solving and plotting the equations of Hoek - Brown ...

This paper presents a methodology for estimating the properties of heterogenous rock masses such as flysch.

A review of underground openings, excavated in varying rock mass types and conditions, indicates that the initiation of brittle failure occurs when the damage index, Di , expressed as the ratio of the maximum tangential boundary stress to the laboratory unconfined ...
