Component characteristics of jointed rock masses

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1975
Abstract In order to use continuum elastic theory for analyzing a multi phase material, such as a jointed rock, certain assumptions are made. These assumptions are necessary so that the component characteristics or moduli can be combined to give the mass characteristics or moduli.

Permeability predictions for jointed rock masses

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1995
Abstract The following problems have been studied: the precolation threshold of jointed rock masses, the Representative Elementary Volume, the permeability of rock masses with impersistent rock joints and the permeability variation with depth. The proposed simple methods are verified against the results of numerical computation and the Stripa Project,

Study on the Strength of Jointed Rock Mass

Key Engineering Materials, 2007
Based on the structure of the rock mass surrounding a highway tunnel under construction, a new methodology for defining the strength of jointed rock mass is proposed. The laboratory experiments and numerical simulations of rock samples, including both intact rock and rock with a single typical joint, are carried out to ensure that the mechanical ...

Mechanical model for a jointed rock mass

Hydrotechnical Construction, 1970
When a rock mass weakened by a system of parallel horizontal joints is loaded at the surface, some settlement, comprised of the displacement due to deformation of the weathered material and the result of drawing together of joint edges, may take place.

Estimating the Strength of Jointed Rock Masses

Rock Mechanics and Rock Engineering, 2009
Determination of the strength of jointed rock masses is an important and challenging task in rock mechanics and rock engineering. In this article, the existing empirical methods for estimating the unconfined compressive strength of jointed rock masses are reviewed and evaluated, including the jointing index methods, the joint factor methods, and the ...

Stability calculations in jointed rock mass: Dissertation

1989
An isoparametric two dimensional joint element with independent non linear behaviour models for normal and shear stress has been used to study different failure criteria and the accuracy of calculations.Testing of the behaviour models indicated similar results obtained by other researchers with different finite element codes.JRTEMP is the first finite ...
