Rockfall Protection, Attenuator Systems, Impact AnalysisAbstract
Attenuators are a rockfall protection solution that combines a flexible rockfall barrier with a block-guiding membrane. To date, there are no formal solutions for their sizing. Compared to classical flexible rockfall protection barriers, which consider only translational kinetic energy and completely stop the block, attenuators present a design challenge where both the rotational and translational components of the falling block's velocity must be considered. Furthermore, attenuator systems are not intended to stop the block entirely; their function is to modify its trajectory and moderate its speed. To develop a sizing concept that addresses these dynamics, it is crucial to fully understand the attenuation process.
A joint program between Willis & Norrish Rock Engineers (Canada), Geobrugg North America, and Geobrugg (Switzerland) has investigated this process in detail. The load on the system, the attenuation processes, and the importance of the rotational component were analyzed in a series of full-scale tests over a period of three years at the Hope BC quarry in Canada. This contribution provides information on the analysis of the loading mechanisms acting on the attenuator system during block impact. The block's movement dynamics are compared between results extracted from sensors integrated into the test blocks, high-speed video analysis, and fall simulations using specialized software.
