FAILURE BEHAVIOR OF HIGHLY STRESSED ROCKS UNDER QUASI-STATIC AND INTENSIVE UNLOADING CONDITIONS (2013)
Li J. , Fan P. et al.  
<p>Unloading failure of rocks, especially highly stressed rocks, is one of the key issues in construction of underground structures. Based on this, analytical models for rocks under quasi-static and intensive unloading conditions are established to study the ...

NUMERICAL SIMULATION OF SHEAR FRACTURE EVOLUTION IN LABORATORY-SCALE SAMPLES (2012)
This investigation aimed to simulate the experiments performed by Nic Gay (Gay, N.C. 1976. Fracture growth around openings in large blocks of rock subjected to uniaxial and biaxial compression. International Journal of Rock Mechanics and Minining Sciences ...

ENHANCED CHARACTERIZATION OF A SOFT MARL FORMATION USING IN SITU AND LAB TESTS, FOR THE PRESTRIPPING PHASE OF COBRE LAS CRUCES OPEN PIT MINE (2009)
This paper describes the lab and in situ site characterization works performed. In order to characterize as accurately as possible these marls, different levels in depth have been distinguished.

STRESS SENSITIVITY OF STYLOLITE MORPHOLOGY (2009)
<p>Stylolites are rough surfaces that form by localized stress-induced dissolution. Using a set of limestone rock samples collected at different depths from a vertical section in Cirque de Navacelles (France), in this paper is studied the influence of the ...

APPLICATION OF MODIFIED HOEK-BROWN TRANSITION RELATIONSHIPS FOR ASSESSING STRENGTH AND POST YIELD BEHAVIOUR AT BOTH ENDS OF THE ROCK COMPETENCE SCALE (2008)
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 ...

HOEK-BROWN FAILURE CRITERION: 2002 EDITION (2002)
<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 ...

CASE HISTORY OF EAST TENNESSEE KARST, STATIC STABILITY OF SOME SHALLOW CAVES (2001)
A case history of a static evaluation of some shallow caves in the karstic geologic region of East Tennessee is presented. The evaluation consists of three parts: (1) characterization of the bedrock voids and openings, (2) rock characterization, and (3) finite ...

ESTIMATING THE GEOTECHNICAL PROPERTIES OF HETEROGENEOUS ROCK MASSES SUCH AS FLYSCH (2001)
This paper presents a methodology for estimating the properties of heterogenous rock masses such as flysch.

ON THE USE OF DIRECT AND INDIRECT METHODS IN DEFINING GEOMECHANICAL PROPERTIES OF WEAK AND COMPLEX ROCK MASSES - APPLICATION, BORZOLI CAVERN (1998)
The proposed approach combines geomechanical characterization, with the results of in situ testing, and back analysis. Especially for in situ testing, a new method is developed for obtaining in an efficient and economic manner specimens of weak rocks. The ...
