ABSTRACT: The Ripley Landslide is located along a strategic railway transportation corridor in British Columbia. It moves along a discrete shear surface at a rate between 25 and 180 mm/year, making it a very slow landslide. The importance of a proactive risk mitigation strategy for the landslide lies in the potential consequences to the railway transportation network if a sudden downslope movement occurs. A downhole ShapeAccelArray (SAA) has been installed to enhance the real time monitoring capabilities of a previously deployed Global Positioning System (GPS) monitoring system. Also, ground-based LiDAR and Satellite InSAR are being used to monitor changes in the slope’s surface shape and displacement patterns. A preliminary assessment of the compatibility between the displacements measured with all of these technologies at the Ripley Landslide suggests that a reliable and comprehensive hazard management approach can be achieved through a monitoring and early warning system that combines different technologies.
RÉSUMÉ: Le Ripley Landslide est situé le long d'un corridor de transport stratégique en Colombie-Britannique. Elle glisse le long d'une surface de cisaillement discrète à un taux compris entre 25 et 180 mm/an, ce qui en fait un glissement de terrain très lent. L'importance d'une stratégie d'atténuation des risques proactive pour la lame se trouve sur les conséquences potentielles pour le réseau de transport ferroviaire si un mouvement brusque vers l'aval se produit. A cet effet, un ShapeAccelArray fond (SAA) a été mis en œuvre pour améliorer les capacités réelles de contrôle du temps d'un système de suivi GPS précédemment déployé. Aussi, LiDAR terrestre et satellite InSAR sont utilisés pour surveiller les changements dans la forme de la surface et de déplacement des modèles de la pente. Une évaluation préliminaire de la compatibilité entre les déplacements mesurés avec toutes ces technologies à la diapositive Ripley suggère qu'une approche de réduction des risques fiable et complète peut être obtenue par un système de surveillance et d'alerte précoce qui combine différentes technologies.
