| Abstract: |
During the design work for the permit application for the approximately 27.3 km long new Semmering Base Tunnel between Gloggnitz and Mürzzuschlag, it has become apparent that due to its extent, the section through the Graßberg-Schlagl fault system will be more problematic than had been assumed during the route selection process. The article discusses the technical possibilities for the construction of the running tunnels through the fault zone. Support concepts with a second layer of shotcrete and short ring closure are investigated using numerical, timedependent calculations. The time dependence is influenced by the advance-rate and the consolidation of the fault material. The determination of the rock characteristics for the core fault zone is based on triaxial compression tests. |
