Attenuators for controlling rockfall: first results of a state-of-the-art full-scale testing program

Rockfall attenuator systems are becoming one of the more popular systems for rockfall mitigation. These systems are proven to be effective; however, full-scale testing with instrumentation has not been performed to the level of traditional rockfall barriers. A joint testing program is being carried out by Wyllie & Norrish Rock Engineers Ltd. and Geobrugg North America, LLC to measure and validate the performance of hybrid attenuator rockfall nets. A preliminary round of full-scale testing was performed in January 2015 and was continued with an extensive program in 2016 at the Nicolum Quarry in Hope, BC. The tests were documented with a high speed camera, load cells on the support cables, and rock motion sensors in the steel reinforced concrete cubes. This paper will present more detailed results of the extensive 2016 program where 84 rocks were rolled into different attenuator systems.
