ABSTRACT: Landslide hazard management at the Downie and Beauregard landslides is achieved by continuous monitoring and analyses of slope behaviour. These massive instabilities have extensive histories of slope monitoring and observational assessment and, in both cases, detailed investigations of geology, geomorphology and hydrogeology. Based on field data sophisticated three-dimensional numerical models have been developed to reproduced observed slope behaviour. This paper reviews the model calibration process which has improved the understanding of geomechanical conditions controlling slope kinematics. Calibrated models are used in ongoing research into how trigger scenarios may accelerate deformations at Downie and the effectiveness of proposed slope drainage at Beauregard.
RÉSUMÉ: L'administration des dangers aux glissements de terrains Downie et Beauregard est réaliser avec un système de surveillance continuelle et les analyses du mouvement de terrain. Ces blocs massives ont eu une programme de surveillance du mouvement de terrain et l'évaluation observationnelle historique extensive et en chaque cas, des investigations de la géologie, la géomorphie et la hydrogéologie. Après les données du domaine, des modèles numériques sophistiqués à trois dimensions ont été développé pour reproduire les mécanismes observés du terrain. Cet article revue le système de calibration du modèle qui avais aidé a mieux comprendre les conditions géomechaniques contrôlant les mécaniques du mouvement de terrain. Les modèles calibrés sont utilisés dans la recherche en cours expliquant comment les déclanchements de scenario peuvent accélérer la déformation à Downie et l'efficacité d'un système de drainage de terrain proposé à Beauregard. 1 INTRODUCTION
