Rockfall canopy for 2000 kJ with self cleaning effect, protecting Tunnel des Pontis portal area

落石防护 - Tunnel des Pontis 2010

Overview of the situation before installation - visible slope with rockfalls up to 2000 kJ of dynamic energy, endangering cantonal road below

落石防护 - Tunnel des Pontis 2010

Designing this unique rockfall canopy, Geobrugg specialists used also simulation software FARO, allowing the structure not only to be 100 percent safe but also have certain self cleaning effect

Rockfall canopy installation required temporary road closure and involved rope access works. Total installation time of two months is short compared to other solutions like concrete gallery

情况

The entrance of the historic Tunnel des Pontis was endangered by rockfalls.

描述

The flexible rockfall canopy – at present the world’s strongest, with an energy absorption capacity of 2000 kJ – was installed at an approximately 60 m long rockface at the Tunnel des Pontis. The supporting structure calculations including special load cases such as boundary field hits, suspension rope hits and snow load were fully simulated on a computer using the FARO software. A total netting coverage of 1200 m² was installed. Lengthening the existing tunnel would have cost eight times more than Geobrugg’s solution.
