Schanztunnel

Tunnel Engineering in BIM

The 860-meter-long single-track tunnel leads through gypsum Keuper rock strata with an overlying ground depth of up to 90 meters. The Keuper rock contains anhydrite, which swells substantially with water ingress. This has caused the tunnel floor to be continuously lifted, consequently it had to be lowered numerous times over the tunnels 140-year history. Maintaining the tunnels serviceability is no longer viable: It has to be replaced.

As part of an engineering consortium, ZPP has been awarded the planning & design services and surveys to develop possible options for replacing the tunnel. For SOCOTEC Germany this means another infrastructure project that will sustainably secure and improve mobility in Germany.

SD Ingenieure was commissioned with the object and structural planning for the tunnel renewal as part of an engineering consortium. In a first stage, renewal variants are being investigated and weighed up against each other.
