... and solute transportation, and is also necessary for the evaluation of extractable ground water and further underground usage. As far as a fracture rock mass is concerned, groundwater always flows through fracture planes. The hydrogeological characteristics of such a rock dominate by the fractural network...

... of the shear fracture planes to the loading axis increases with the confining pressure and the peak strength increases with the increasing of confining pressure. It can be found that the significant effect of intermediate principal stress on the peak had two zones in true triaxial compression tests...
