Short summary
A theoretical model of the Compression of the Damaged Zone experiment performed is proposed. One of the key features of the present model is its ability to yield the crack closure. The mechanical and hydric effects are examined seperately: in one case a prescribed pressure is applied at the drift wall, and swelling strains in the cracked zone are introduced in the other to model its resaturation. The intensity of the crack closure is heterogeneous in both cases but is greater in the latter.
