Résumé

Natural discontinuities (eg, joints, faults, and bedding planes) are generated through long-term geological processes. The mechanical response of rock mass is known to be greatly impacted by these discontinuities. The existence of these discontinuities has been the principal obstacle to estimate precisely the deformability and stability of rock masses in practical engineering design. Thus, better interpretation of such influence is essential to investigate aiming at achieving realistically mechanical response of geo-materials. Up to now, it has been reported that the formation of these discontinuities most likely correlate with fracture initiation, propagation, and coalescence. More effort therefore has been made to gain better understanding of the mechanism of fracture propagation based on the theoretical analysis 1-6 and available experimental tests. 7-16 These data show that not only the peak strength (at failure) but the
