Geomechanical Design of Long Tunnels using Databases

The Brenner Base tunnel with its approximately 55 km length is a highly complex and ambitious project. The geomechanical design of such a tunnel system demands flexible tools to be able to cope with adoptions and modifications. The following paper describes the preprocessing of the given data, the setup of the database and the structure of the information processing. The different data are processed in order to get the full information for the tunnel system for each meter. This extensive information is used by the cost estimators. Then the data are condensed to have the information in the structure needed for the geomechanical design reports.
