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.

This technical note examines the reliability of a slope stability calculation and a tunnel support design calculation, using rockmass strength and deformation characteristics estimated by Hoek - Brown procedure.

This paper summarizes the interpretation of the Hoek-Brown failure criterion which has been found to work best in dealing with practical engineering problems.<br>

This paper presents an early version of the GSI classification.
