ABSTRACT: The External Tailings Facility dyke at the Muskeg River Mine north of Fort McMurray has been under construction since 2000. Data from piezometer installations within the tailings dyke foundation provide a unique opportunity to investigate the effect of staged construction on the generation and dissipation of excess pore water pressure within the foundation clayey units. In this study, pore water pressure generation data for the clayey facies of the foundation was compiled. Piezometric data were used to estimate the dissipation parameters for the clayey units at a selected zone of the foundation. Explanations were provided for spatial and temporal variations in the pore water pressure generation parameters.
RÉSUMÉ: La digue de l'Installation externe de rejets à la mine de la rivière Muskeg, au nord de Fort McMurray est en construction depuis 2000. Les données tirées des installations de piézomètres à l'intérieur de la fondation de la digue de rejets constituent une occasion exceptionnelle d'examiner l'effet de la construction par étapes sur la production et la dissipation de pression d'eau interstitielle excessive à l'intérieur des unités argileuses de la fondation. La présente étude a compilé les données de production de pression d'eau interstitielle pour le faciès argileux de la fondation. Les données piézométriques ont été utilisées pour estimer les paramètres de dissipation des unités argileuses d'une zone sélectionnée de la fondation. Des explications ont été fournies pour les variations spatiales et temporelles des paramètres de production de pression d'eau interstitielle. 1 INTRODUCTION
