Modélisations couplées Hydro-Mécaniques en milieux poreux partiellent saturés : application à la ventilation de galeries profondes

Abstract : During the last decades, the study of coupling phenomena became more and more important in Geomechanics and Civil Engineering. Radioactive wastes repository in deep geological formation is a perfect illustration of this kind of problems. Indeed, due to numerous stakes, all acting phenomena must be considered in order to determine the first fonctionnality of the repository structure: the full safety confining of radioactive wastes. During the building period of the repository structures, the excavation and the ventilation of galleries induce solicitation of the surrounding rock mass. The abject of this work is to characterize the importance .and the nature of this solicitation. It's fundamental to determine the phenomena kinetics (progression of the drying front induced by ventilation, the extent of the perturbated zone) and the strengh of induced couplings (stresses in front of gallery, damage). The aim of all this considerations is to evaluate the eventual modifications of the rock and its confining abilities. The theoretical approach is the Mechanics of Porous Media defined by Coussy (1995), which leads to a formalism at the macroscopic scale and allows to determine the evolutions of the rock, considered as partially saturated porous medium (three-phases medium). The aim of the different models presented in this work is to describe the fluids transfers in the rock mass and to take into account constitutive aspects of the mechanical behavior of the rock (damage, plasticity).
