Desde nuestra primera estructura de prevención de avalanchas en 1951 hemos continuado con el desarrollo de mejores sistemas de protección de año tras año. Nos desafiamos a nosotros mismos para mejorar constantemente; por lo tanto, nuestras soluciones se han convertido en el estándar.


Advanced Modeling and Simulation of Rockfall Attenuator Barriers Via Partitioned DEM-FEM Coupling, 2021

Advanced Modeling and Simulation of Rockfall Attenuator Barriers
Attenuator barriers, in contrast to conventional safety nets, tend to smoothly guide impacting rocks instead of absorbing large amounts of strain energy arresting them. It has been shown that the rock’s rotation plays an important role in the bearing capacity of these systems. In order to support the engineer’s design decision, reinforce test results and confidently predict barrier performance beyond experimental configurations this work describes an appropriate numerical modeling and simulation method of this coupled problem. For this purpose, the Discrete Element Method (DEM) and the Finite Element Method (FEM) are coupled in an open-source multi-physics code.

Full-scale testing of rockfall nets in real terrain (below Innosuisse Project 2019)
Rockfall impacts with a flexible barrier include both translational and rotational kinetic energy. Traditionally rotational energy is not included in barrier design.The dissipation of translational kinetic energy has been considered only in idealized conditions, such as free-fall experiments. To study how rockfall barriers absorb rotational and translational energies in realistic conditions we performed a series of full-scale rockfall tests in natural terrain. The presented methodologies pave the way to a comprehensive understanding of rock-ground and rock-net interaction, a key requirement to improve the design of flexible barriers that account for the role of rock shape, spin and eccentric impacts in rockfall protection.

Nuevo estándar de la FIA: Geobrugg Motorsport Fences primero en ser homologado

New FIA Standard: Geobrugg Motorsport Fences first to be homologated
FIA (Fédération Internationale de l’Automobile) governing body of the motorsport introduced a new standard with performance criteria. The first homologated products are the Geobrugg motorsport fences: the Debris Fence and the Mobile Debris Fence meet the requirements of FIA Standard 3502-2018 debris fence.

Flexible debris flow barriers and their service ability proof
The first research on a serviceability method for scour and erosion issues on flexible debris flow nets. Design and calculation will be more economically and safely, maintenance costs will be minimized and a longer lifetime of the entire barrier system, including anchors as the most cost-intensive parts, can be provided. Impressions of the small field tests.

Innosuisse project: Rockfall Tests
In order to obtain new measurement data to improve the design of rockfall protection nets and the SLF rockfall simulation programme, SLF researchers and Geobrugg are testing at the Flüela Pass.


World's first dimensionable attenuator system
Geobrugg developed together with international experts an attenuator protection solution which can be efficiently dimensioned. This innovative rockfall protection is a modified rockfall drape providing particularly efficient protection. It was presented in British Columbia/Canada in August 2018.

Geobrugg Dimensioning Software: Updates
RUVOLUM® (launched in 1999), DEBFLOW, SHALLSLIDE or SPIDER® online tool offer new functions e.g. 3D view, larger selection of nails, recommended nail inclination, anchor-plate assembly or additional drawings illustrating the acting forces and indicate the crucial parameters.

RXE-500 rockfall barrier with ETAG 027 approval
RXE-500 rockfall barrier has become ETA-certified for heights between 3 and 5 meters. In the 100 kJ to 8000 kJ energy classes we offer protection systems stringently tested and approved in all standard heights. All RXE systems are certified both by EOTA and FOEN guidelines and bear the CE-certificate.
