Lernen und Optimieren vom Erkundungsstollen – Brenner Basistunnel
Description:
<jats:title>Abstract</jats:title><jats:p>The Brenner Base Tunnel, which is 64 km long from the portal in Tulfes to the portal in Fortezza, consists of two main tunnels and a continuous exploratory tunnel. The exploratory tunnel, located between the two main tunnels, is used during the construction phase for the investigation of the rock mass, thereby reducing the risks of the construction of tunnels. During operation, the exploratory tunnel will serve as a drainage tunnel and will be fundamental for the maintenance of the entire system. At the moment, almost 50 % of the total distance of the exploratory tunnel length has already been completed. This paper first includes a report on the status of the works at the exploratory tunnel, with details of the stretches that have already been driven and the main results of exploration work. The paper also concerns ”Learning from the work on the exploratory tunnel“, with a description of the objectives and methods of exploration activities. ”Optimization“ is a further topic. Several examples are given here how the data gleaned from the exploratory tunnel are used in building the main tunnels.</jats:p>
