DETERMINATION OF THE DAMAGED ZONE IN QUARRIES, RELATED TO AGGREGATE PRODUCTION

Jern M. (2001)

To make quarrying profitable, the blasting should effectively disintegrate the rock mass whilst at the same time minimising damage to the individual rock fragments. The zone of damage around blast holes has been considered ...
EXPERIMENTAL STUDY OF MECHANICAL BEHAVIOUR OF ROCK JOINTS UNDER CYCLIC LOADING

Jafari M.K.; Pellet F.; Boulon M.; Hosseini K.A. (2004)

Evaluation of the effects of small repetitive earthquakes on the strength parameters of rock joints in active seismic zones is of interest of the designers of underground constructions. In order to evaluate these effects, ...
THE ROLE OF OFF-FAULT DAMAGE IN THE EVOLUTION OF NORMAL FAULTS

Manighetti I.; King G.; Sammis C.G. (2004)

Recent measurements of slip profiles on normal faults have found that they are usually triangular in shape. This has been explained to be a consequence of on-fault processes such as slip-dependent friction. However, the ...
TWO-PHASE DAMAGE THEORY AND CRUSTAL ROCK FAILURE: THE THEORETICAL 'VOID' LIMIT, AND THE PREDICTION OF EXPERIMENTAL DATA

Ricard Ya.; Bercovici D. (2003)

Using a classical averaging approach, we derive a two-phase theory to describe the deformation of a porous material made of a matrix containing voids. The presence and evolution of surface energy at the interface between ...
