... in 1995, the 1·8 km long, 8·4 m dia. tunnel has been built to accommodate double-stack container trains and replaces an existing century-old tunnel link. The concretelined tunnel was driven by one of the largest ever full-face earth pressure balance machines through soft squeezing clay with shallow cover...

.... In difficult ground conditions the temporary support of the face and the excavation method both derive from the type of TBM used. This tunnel could probably not have been constructed 20 years ago. With today's state-ofthe-art the choice was clearly between a slurry tunnelling machine or an earth pressure...

The primary precast concretebolted segmental lining was designed to carry the full earth overburden pressures. After...
