Schotcrete as permanent lining for the Furka base tunnel
Summary The lining concept of the 15.4 km long one-track Furka railway tunnel is described with particular emphasis on shotcrete application as a permanent support Altogether 70000 $ m^{3} $ dry aggregate/ cement mix and 115000 rock bolts have been applied. The tunnel was lined at a rate of approx. 400 tunnel metres per month using up to five shotcrete machines simultaneously. Systematic quality control throughout the construction work indicated an average uniaxial compressive strength of shotcrete of 40 N/$ mm^{2} $. The support requirements were grouped into 16 different classes and an additional special class accounting for extreme geological conditions in some relatively short stretches.
