ABSTRACT: Ice roads remain a vital transportation link for remote communities and industrial sites in the northern and arctic regions of Canada. Most of the guides and practices for safe operation of ice roads rely on ice bearing capacity charts published by Lorne Gold in 1971. However, this state of practice for ice road design and operations has not taken full advantage of developments in GPR ice profiling, bearing capacity analysis and risk management. This paper presents a risk management framework for ice roads to identify the hazards, assess the risks, develop appropriate risk strategies, and monitor, evaluate and adjust the risk strategies. In an example we show how GPR ice profiling provides more confidence in the characterization of ice thickness used in bearing capacity analysis. The risk management framework allows greater flexibility in managing risk by recognizing the role of design parameters, operational controls, and quality assurance programs.
RÉSUMÉ: Les routes de glace demeurent un lien essentiel pour les communautés éloignées et les sites industriels dans les régions nordiques et arctiques du Canada. La plupart des guides et pratiques pour une exploitation sécuritaire des routes de glace se basent sur les tables de capacité portante de la glace publiés par Lorne Gold en 1971. ne prend pas avantage de la technologie du Géoradar qui permet un profilage géologique de la glace, une analyse plus précise des capacités portantes en améliorant donc la gestion des risques. Ce document présente un cadre de gestion des risques liés aux routes risques, élaborer des stratégies de risques appropriés ainsi que de surveiller, évaluer et ajuster les stratégies de risque. A travers un exemple, nous montrons comment le Géoradar fournit une analyse qualitative de l'épaisseur de la glace dans l'étude de ses capacités portantes. Le cadre de gestion des risques permet une plus grande flexibilité dans la gestion des risques en reconnaissant le rôle des paramètres de conception, des contrôles opérationnels et des programmes d'assurance de la qualité.
