Comportement hydromécanique des géomatériaux : applications aux ouvrages souterrains

Abstract : Research presented here is justified by several problematics in relation to the geoenvironmental applications: post-mining with regard to the mechanical stability of the abandoned mines due to a progressive rise of ground water after the end of the dewatering process; the deep underground storage of hydrocarburs or radioactive wastes. The approach adopted in this research consists to jointly undertake an experimental study, a theoretical modeling of physical phenomena (conceptual and numerical developments) and in situ applications. On the basis of the laboratory tests and/or in situ experiments carried out on several geomaterials (iron ore, claystones and granite; rock joints of granite, schist and sandstone), several conceptual models and rheological laws were developed. These constitutive models were also implemented in numerical codes and applied to interpret specific in situ experiments and to perform retro-analyses with confrontations between measurements and predictions. The practical applications involve structures of deep underground radioactive waste repository (such as the underground laboratory of Meuse/Haute-Marne in France) and the mining works. The details of methodology and the applications carried out are widely discussed in Souley (2010). Three examples are illustrated here: (a) a new experimental device allowing to characterize the hydraulic exchanges between fracture and matrix in a double porosity environment, (b) the developments of a macroscopic viscoplastic model of argillites aimed to improve the viscoplastic strain prediction in the EDZ (Extent of Damaged Zone) around the LS/MHM drifts are proposed based on the in situ observations, (c) the modeling of REP experimentations (including the hydromechanical behaviour) at the underground laboratory of Meuse/Haute-Marne (LS/MHM).
