Modélisation de la stabilité des massifs rocheux avec prise en compte de l'endommagement des joints et des effets hydromécaniques

Abstract : The damage of non-persistent rock discontinuities and hydromechanical effects are two key phenomena in rock mass stability. Based on experimental results (literature), a new constitutive damage-plastic joint model has been proposed to model fracturing in quasi-brittle materials along a predefined surface. This model, takes into account the progressive degradation of strength and stiffness of joints in both normal and tangential directions. It considers irreversible relative displacements, tangential residual strength and the nonlinear behavior of joints. The model reproduces well the experimental results when implemented in the finite element code CESAR-LCPC. In order to performing coupled hydromechanical analysis, a computing module of stationary flows in fracture networks has been developed, as well as an interface between the module and CESAR-LCPC code. The developed numerical tools were applied to study rock slope stability of the "Rochers de Valabres" (ANR - STABROCK project).
