The use of subsurface structures is one of the key factors in the sustainable development of both industrial and emerging/developing nations. Subsurface transalpine traffic routes, the tendency towards larger diameters, difficult geological conditions and high groundwater pressures pose new challenges to tunneling and excavation technologies.

In his presentation Prof. Anagnostou will dicuss the stability of the tunnel face on the basis of the latest scientific findings. The presentation of Dipl.-Ing. Heinz Ehrbar gives insights in the construction of the Gotthard Base Tunnel and suggests conclusions for future large-scale tunneling projects.
