Preliminary works for the new Semmering Base Tunnel – geotechnical monitoring of slope stabilization measures and earth retaining structures

In preparation for the construction of the new Semmering Base Tunnel, which will reach a length of 27.3 km, comprehensive preliminary measures had to be completed. As a part of Contract Section SBT2.3, several slope stabilization measures, as well as earth retaining structures and ramps using the reinforced earth method, were constructed.

This contribution will give an overview of the construction measures, as well as of the systematic geotechnical monitoring that was implemented as part of the geotechnical safety management program.
