The system's adaptability means that posts can be positioned on ridges with center-to-center distances of up to 16 m, reducing the number of posts and anchors required

Steinschlagschutz - Viaduc du rocher de Larce - RN5 2024

5,000 m² of protection with excellent visual integration of the system. Thanks to the use of high-tensile steel wire mesh, the number of posts could be reduced, and energy dissipators were not necessary.

Ausgangslage

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.).

Massnahme

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.
