<p>In this paper, a numerical code, RFPA2D (rock failure process analysis), was used to simulate the initiation and propagation of fractures around a pre existing single cavity and multiple cavities in brittle rocks. Both static and dynamic loads were applied ...

<p>Natural open joints in rocks commonly present multiscale self-affine apertures.The goal of this paper is to find a geometrical model of the complex aperture that describes at best the macroscopic properties (hydraulic conductivity, heat exchange) with the ...

Infill materials found in natural rock joints may cause a reduction in joint shear strength, influencing rock mass stability. This paper reports a study aimed at developing a semi-empirical methodology for predicting the shear<br>strength of infilled joints, ...

This study includes conducting diametrical compression tests on notched Brazilian disk specimens. Moreover, the effect of confining pressure and temperature on crack initiation and propagation were also studied. The experimental results were compared with ...

This paper provides a review of hydromechanical (HM) couplings in fractured rock, with special emphasis on HM interactions as a result of or directly connected with human activities.

This study aimed to extend the understanding of multiphase flow by conducting nitrogen-water relative permeability experiments on a naturally-fractured rock from The Geysers geothermal field.

Soil-infilled discontinuities adversely influence the stability of rockmass, because, the infi ll materials especially when saturated, drastically reduce the shear strength. The angle of shearing resistance of a discontinuity decreases significantly for increasing ...

<p>This paper summarizes some of the basic assumptions about strength of rock masses. A simple empirical failure criterion is presented and its application in engineering design is illustrated by means of a number of practical examples.</p>

<p>Experimental results in the published literature show that at low normal stress the shear stress required to slide one rock over another varies widely between experiments. This is because at low stress rock friction is strongly dependent on surface roughness. ...
