Situation de départ

The Swiss National Road No. 17 between Weesen and Amden was endangered by stone and block striking. Between autumn 1978 and August 1981 the  Mattstock Gallery with a length of 110 meters and the Churfirsten Gallery with a length of 155 meters were created.

After various rockfall events and activities the danger situation of the whole street section was checked. The static calculation showed that the two galleries would only cover energies of 300 to max. 500 kJ as standard.

Based on a risk assessment, it was decided to fortify the two galleries for the scenario with a probability of a recovery period of 10 to 30 years with energies of 200 to 1'900 kJ.
