Situação:
During construction of the headrace tunnel in July 2012 for a hydro power plant some severe rockburst occured. The high internal stress in the rock and overburden over 1000 m on top of the tunnel as well as the brittle metamophic character with a rock mass rating RMR › 65 caused some severe problems during the project.
Descrição:
The tunnel was divided in sectors to analyse the stress level in regard to the high stress classification whereas it shows that some rockbursts of level 2 and 3 occured. In the most critical zone a support system with MINAX® 80/4 was applied in combination with mechanized installation thanks to Geobrugg's MESHA® handler. The installation time had been decreased between 20 to 25% and safety for workes was significantly improved.
