... in the Gotthard base tunnel, Switzerland and the Koralm Tunnel, Austria: The agreement is well, within ±15%. Reliable simulations call for a solid data base; e.g. surface temperatures, basal heat flow and uplift/erosion patterns must be determined beforehand. The range of geothermal and hydrogeologic properties...

... in the Sedrun section of the Gotthard Base Tunnel, where heavy squeezing conditions were encountered (Mezger et al. 2013). It was shown that the variability of the squeezing intensity along the tunnel could be traced back to a variable degree of tectonic shearing, variable schistosity orientation with respect...

... Abstract This paper will provide an overview of mechanized tunnel boring methods implemented at major alpine railway tunnel construction projects in the past years. A focus will be on the Amsteg/Erstfeld Lot (Gotthard Base Tunnel in Switzerland) and the Koralmtunnel Lot 2 in Austria. The lots...
