In the underground waste isolation projects such as the ANDRA'one in the site of Bure, the transport properties of the surrounding rock mass is of fundamental importance. To measure very low permeability, we use the modified version of the pulse test

Publikováno v: Engineering Geology. 64:117-133

The hydromechanical properties of the rock masses in the upper part of the Earth's crust are strongly governed by the presence of rock discontinuities. For this reason, experimental investigations have been made on calcite-healed discontinuities of a

Publikováno v: International Journal of Rock Mechanics and Mining Sciences. 36:1001-1012

This paper deals with numerical modelling of induced damage in three granites. A continuous anisotropic damage model is proposed in the framework of thermodynamics and fracture mechanics. A second rank tensor is used to describe damage state which is
