TECHNICAL STANDARDS FOR DEBRIS FLOW BARRIERS AND BREAKERS



Abstract:
Debris flow barriers and breakers protect human settlements, infrastructure and supply lines from torrential disasters by dissipating the energy of debris flow (floods), dosing (filtering) coarse solid components and deflecting the flows from the areas at risk. The function and design of these structures has to follow the principles of the EUROCODE standards. In order to establish a comprehensive “state-of-the-art” for torrent control engineering an interdisciplinary working group (ON-K 256) was established at the Austrian Standards Institute (ASI) in 2006, which develops new technical standards for load models, design, dimensioning and life cycle assessment (technical standard ONR 24800 - series). The paper summarizes the state of development concerning the function and design of debris flow barriers and breakers.
