Vibration monitoring during constructionPDF-Download
The Brenner base tunnel is a central element of the new high-capacity axis for the Berlin-Palermo railway line and is meant primarily for goods transport.
The exploratory tunnels are being excavated for the purposes of geological and hydrogeological prospecting and exploration. This preliminary research will help to minimise construction costs and risks.

The environmental impact assessment of the Brenner base tunnel resulted in the requirement for continuous vibration monitoring during the construction of the exploratory tunnels. This involved the placement of monitoring devices in residential buildings and in various installations (“Sillschlucht” power station, motorway bridges, existing ÖBB tunnel, funicular etc.). Data were transferred by remote data link to a central data base and could be accessed by the project team via an Internet platform.
A web-based data base had to be programmed specifically for the project. This data base displayed all monitoring data – including concluded measurements – for the client, designers and contractors. Some measurements had to be performed under very difficult conditions, for example in the existing Innsbruck bypass tunnel of the Austrian Federal Railways (ÖBB) and in the installations of the “Sillschlucht” power station of the Innsbruck municipal power company IKB.
