N2 - The pore pressure evolution induced by excavation of drifts is analyzed by means of a fully coupled hydro-mechanical finite element simulation. The main goal is to simulate the principal trends of the pore pressure evolution with a simple model taking into account the inherent anisotropy of the material and the anisotropy of the initial stress state. The influence of the degree of anisotropy of the rock on the overpressures induced by the excavation is analyzed. The influence of the hydro-mechanical coupling on the development of the failed zone around drifts is also discussed.
