The presence of complex discontinuity patterns, the inherent statistical nature their geometrical parameters, uncertainties involved in estimation and geo-mechanical properties three dimensional (3-D) in-situ stress make accurate prediction rock mass strength a difficult task. It has been great challenge for mechanics engineering professions to develop criterion dimensions that incorporates eff...

In this paper, we study the anisotropy effect in IP data in the context of the generalized effective-medium theory of induced polarization (GEMTIP). The effective-medium conductivity defined by the GEMTIP model, in a general case, is represented by a tensor function. This tensorial property of the effective-medium conductivity provides a new insight on the anisotropy phenomenon in the IP effect...

In the construction project, rock mass is often destroyed from joint plane, and jointed easy to be eroded by freeze-thaw environment. Therefore, damage mechanical properties of filled under action are very important for disaster prevention, engineering safety evaluation reinforcement. order research effect cycle on deterioration characteristics rocks, prefabricated samples tested with different...

We consider the behavior of immiscible and incompressible two-phase ows in a porous medium made of several rock types. Each rock type, is deened by one porosity, one absolute rock permeability ten-sor, two relative permeability curves and one capillary pressure curve. Using two-scale convergence, we get an homogenized model which governs the global behavior of the ow. In this model, macroscopic...
