Steep Geosynthetic-reinforced Slopes Stabilize Access Routes for Construction of 27-km Tunnel

The construction of the Semmering Base Tunnel, located in Austria, is presented in this article. Once the tunnel is completed in 2024, it will eliminate one of the main infrastructure bottlenecks along the Baltic - Adriatic Axis (BAA). The uninterruped route for rail traffic between Gdansk, Poland and Ravenna, Italy is expected to generate significant economic momentum for the adjoining regions. The project required extensive enabling works, including the construction of steep geosynthetic-reinforced slopes to stabilize the access and haul roads near the Longsgraben spoil tip (the municipality of Spital am Semmering). Because of the difficult terrain, there was a need to reuse local tunnel spoil and to relocate a stream bed. The project consisted of many geotechnical challenges and these challenges are described.
