[en] This paper is concerned with the coupling effects existing between the mechanical problem and the water diffusion process during an excavation, in relation with the nuclear waste disposal concepts. The hydromechanical coupling effects are first evidenced. Then, the permeability variation with damage is studied. Finally, different kind of flow boundary condition are considered. Their influence on the cavity convergence is highlighted and their effect on strain localisation process as well.
