FREUDENSTEIN TUNNEL WEST - HIGH SPEED TO STUTTGART

This article describes the construction of the freudenstein tunnel West, being built on the new high-speed railway between mannheim and Stuttgart, West Germany. The tunnel will be 6.8 km long and has a massive cross section of 160 sq m; it is being constructed by alfred kunz, a German contractor very experienced in tunnelling. Details are given of the (very poor) rock conditions, the method of boring, face drilling, blasting, loading out, and tunnel support. Several factors influenced the designers' choice of a very large cross section single tunnel rather than twin tunnels: (1) the tunnel is designed for a 'life' of 100 years, and it may have to be relined during that period; (2) a large cross section reduces the 'shock effect' of two trains passing at very high speeds; (3) planning approval is more likely to be obtained for twin-track tunnels, because the open cuts are smaller and the amount of spoil is less; (4) twin-track tunnels are always less expensive than twin tunnels in hard rock.
