The synthetic rock mass approach for jointed rock mass modelling
International Journal of Rock Mechanics and Minings Sciences, 2011Abstract This paper describes synthetic rock mass (SRM) modeling, a new approach for simulating the mechanical behavior of jointed rock mass. This technique uses the bonded particle model for rock to represent intact material and the smooth-joint contact model (SJM) to represent the in situ joint network.

Deformation of a jointed rock mass
Geologiska Föreningen i Stockholm Förhandlingar, 1978Abstract The finite-element method and the discrete-block method have been used to study the defor-mational behaviour of a jointed rock mass subjected to simple shear displacement. Blocks in models with large sizes of block make contact at few points which cause large openings of joints and high stress concentrations in the blocks and surrounding ...

Comparison of failure criteria for jointed rock masses
International Journal of Rock Mechanics and Mining Sciences, 2004This paper compares two different failure strength criteria for rock; the popular non-linear Hoek and Brown failure criterion and a simple non-linear failure criterion recently proposed by Ramamurthy. Equivalent continuum analyses of jointed rock masses have been carried out using program FLAC with each selected failure criterion.

Implications of Joint Properties on the Strength of a Jointed Rock Mass
Advances in Unsaturated Soil, Geo-Hazard, and Geo-Environmental Engineering, 2011In order to minimize the environmental and physical hazards of rock slope failures in deep open cut mines, evaluation of rock mass strength with a reasonable degree of accuracy is required. The task is made much more difficult due to the presence of discontinuities or joints, as the strength of a rock mass depends on both the strength of intact rock ...

A constitutive model for jointed rock masses
Journal of the Chinese Institute of Engineers, 1988Abstract The presence of discontinuity in the geological media has long been recognized as an important factor influencing the mechanical behavior of the media. This paper proposed a versatile constitutive law that can model an assemblage of intact rock blocks separated by cleavage, bedding planes, joints, or other types of structural weak planes.

Anisotropy in jointed rock mass breakage
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989Abstract Cracks in a rock material are generally closed and have no volume effect on the rock material's deformational characteristics. These closed cracks, however, markedly effect the rock materials strength. Joints, on the other hand, do have a volume effect on the rock mass's deformational behaviour as well as its strength or stability.
