ABSTRACT: Natural and man-made rock slopes are frequent along the railroad linking Port-Cartier to Fermont. The aim of the ParaChute research project is to integrate various technologies into a workflow for rockfall characterization along linear infrastructures (including roads) and to test its application along a portion of 260 km of this railroad. Our work will focus around different objectives: (1) to optimize the use of terrestrial, mobile and airborne laser scanners data into terrain analysis, structural geology analysis and rock fall susceptibility rating, (2) to further develop the use of unmanned aerial vehicles for photogrammetry applied to rock cliff characterization, (3) to integrate rockfall simulation studies into a rock slope classification system similar to the Rockfall Hazard Rating System and (4) to consider climate change impact on mass movements. With this paper we want to share our approach and preliminary results.

RÉSUMÉ: Les parois rocheuses naturelles et anthropiques sont fréquentes en bordure de la voie ferrée reliant Port-Cartier à Fermont. Le but du projet de recherche ParaChute est d™intégrer diverses technologies de caractérisation des chutes de pierres et de tester l™application de cette approche sur une distance de 260 km du chemin de fer. Notre travail se concentre autour des objectifs suivants : (1) optimiser l™utilisation des scans lasers terrestres, mobiles et aéroportés pour l™analyse de terrain, l™analyse structurale des parois rocheuses et pour la caractérisation de la susceptibilité aux chutes de pierres, (2) continuer de développer l™utilisation d™aéronefs sans pilote pour la photogrammétrie appliquée à la caractérisation de parois rocheuses, (3) intégrer les outils de simulations des chutes de pierres dans un système de classification inspiré du Rockfall Hazard Rating System et (4) évaluer l™impact des changements climatiques sur les mouvements de terrain. Cet article vise à présenter l™approche préconisée ainsi que des résultats préliminaires.
