This paper refers to the proposed western extension of the Athens Metro to Piraeus city. The railway consists of a 9.45 m
diameter, 8.2 km long tunnel and seven stations. Tunnelling works are expected to be undertaken within a variety of lithological
formations ranging from very strong alpine limestones to recent soft littoral deposits. The tunnel alignment was divided into
12 areas with respect to the geological and geotechnical conditions that may be encountered during construction. In many of
these zones, the geotechnical conditions together with the presence of sensitive surface and/or subsurface structures led
to the selection of a closed-face TBM (Earth Pressure Balance Machine or Slurry Tunnel Boring Machine) as the appropriate
tunnelling technique. The Piraeus extension is a project where in places both types of commonly used closed-face tunnelling
machines will encounter ‘text book’ application areas, but not always. The applicability of each type of TBM is discussed
using the available data obtained from an extensive site investigation.
