myGeobrugg
Initial situation
The Morez Viaduct on the RN5 runs for several hundred meters along the Larce rock face. This predominantly rocky slope produces numerous boulder and rock fall events, which are currently channeled and accumulated in aging structures that are inadequate for the phenomena involved (mesh barriers, rope ladders, etc.).
Description
Geobrugg supplied a rockfall attenuator that met several criteria. A study of the area's rockfall hazards provided the input data allowing the use of the ATTERO dimensioning software.
Thanks to the solution’s adaptability and low visual impact, it is perfectly integrated into the viaduct. This attenuator’s optimized composition, with no energy dissipation system (brake), will minimize the need for maintenance intervention.
