ABSTRACT: The soil berm stop butt used to arrest bullets behind targets of Canadian Armed Forces Small Arms Ranges (SAR) infrastructure presents a geotechnical opportunity for optimization. Existing pre-emptive monitoring of the berms over the past decade has established multiple modes of failure. Previously, the initiation for remediation was assessed against a fixed amount of bullet impacts. Using qualitative and quantitative metrics, the deterioration of the soil berm can be assessed over time. The results of this research will be used to optimize and critique, for improvement, the design and use of SARs in an area-wide, national approach. Using LIDAR scanning, the effects of long-term, repetitive ballistic loading will capture the stability of standard soil-clay slopes. Some key characteristics of SAR stop butts including usage, material gradation, surface tunnelling, bullet penetration depth and environmental considerations will be monitored to assess their feasibility as threshold catalysts for routine maintenance of the berm.


RÉSUMÉ: Les butte d’arrêt des champs de tir pour armes légères présente une opportunité géotechnique d'optimisation. La surveillance préventive des bermes au cours de la dernière décennie a établi multiples modes de rupture. Auparavant, le début de la remise en état était évalué par rapport à un nombre fixe d'impacts de balles. À l'aide de mesures qualitatives et quantitatives, la détérioration de la berme peut être évaluée au fil du temps. Les résultats de cette recherche seront utilisés pour optimiser et améliorer le manuel de construction des champs de tire. En utilisant la numérisation LIDAR, les effets du chargement balistique répétitif captureront la stabilité des pentes sol-argile standard. Certaines caractéristiques clés, notamment l'utilisation, la gradation des matériaux, les tunnels en surface, la profondeur de pénétration des balles et les considérations environnementales seront surveillées pour évaluer leur faisabilité en tant que catalyseurs de seuil pour l'entretien de routine de la berme.
