Abstract: |
Deep Alpine tunnels are characterised by great lengths and deep overburden and are mostly bored by TBMs. The exploration of rock mass conditions plays an essential role with regard to the technical feasibility, the estimation of advance rates and the safety and cost-effectiveness of a project. Investigation drilling from the surface is often not possible due to the topographical conditions and the very high cost considering the great depths involved. Most TBMs are therefore designed to permit the exploration of the ground in parallel to continued tunnelling. |
