Abstract: |
In long, deep tunnels, it is not possible to completely investigate the ground conditions along the future alignment in advance. Unexpected ground conditions and fault zones thus have to be accepted as residual risks and overcome by suitable measures. This is also the situation at the Gotthard Base Tunnel (GBT), which is 57 km long with overburden depths of up to 2.350 m. The main contracts included items for systematic advance probing from the tunnel and provided a catalogue of suitable additional measures. These measures were intended to detect and overcome unforeseen ground conditions. |
