Abstract
Difficult ground was predicted for the 6.3 km long Grauholz Tunnel. The geology comprises complex soft-ground above and below the groundwater and rock conditions. The examples described led to the choice of a mixshield machine to excavate the 11.6 m diameter tunnel. This machine can operate in either closed (slurry) or open (TBM) mode. Experiences with this installation are discussed.
