Semmering Base Tunnel, Austria
Abstract Semmering Base Tunnel, a major infrastructure project in Europe, consists of two 27.3 km single-track tubes, numerous cross passages and a complex underground emergency and ventilation station with two 420 m deep ventilation shafts. Intermediate access points include a 1.2 km long access tunnel with two 220 m deep sub-surface shafts for connection to the main tunnels, temporary 100 m deep shafts from the surface and large caverns at the shaft bases. The dimensions of the larger caverns are in the range of 20 m by 18 m. The maximum overburden is approximately 950 m in difficult geological conditions with large fault zones and extensive water inflow, which requires complex heading concepts, extensive support measures and partially special ground improvement works such as grouting. Sophisticated numerical 2D- and 3D-calculations were carried out to verify the adequacy of the designed solutions. Construction using the NATM and TBM method is ongoing from 2014 until 2026.
