ABSTRACT: Two different clay-based sealing materials were examined in the laboratory for understanding the hydro-mechanical (HM) performance of materials as part of the conceptual design of Canadian deep geological repository. Tests were carried in oedometer with several loading schedule and with various concentration of pore fluids. Emphasis was given to evaluate the material parameters under a wide range of pore fluid salinity. Experimental finding provide important material parameters for numerical modeling. These parameters will be used to conduct numerical simulation of the sealing materials using a finite difference based computer code (FLAC).
RÉSUMÉ: Deux différents scellants conformés à l'argile ont été examinés dans le laboratoire pour avoir une meilleure compréhension de la performance hydro-mécanique des matériaux qui font partie de l'étude de conception du dépôt dans des formations géologiques profondes Canadiennes. Des tests d'oedomètre ont été effectués avec plusieurs horaires de chargement et avec divers fluides interstitiels. L'emphase était mise sur une évaluation des paramètres des matières sous une gamme étendue de salinité des fluides interstitiels. L'étude expérimentale fournit les paramètres des matières importantes pour la modélisation numérique. Ces paramètres utilisent une différence finie basée sur le code interne FLAC qui est ensuite utilisés pour diriger la simulation numérique des scellants. 1 INTRODUCTION
