For the conception of the emergency ventilation and the design of the ventilation system for the New Semmering Base Tunnel, particular demands apply, which are based on specific protection objectives and defined in the Tunnel Safety Concept. The main objective is to keep the safe areas (the refuge room at the emergency station, opposite tube, portals) free of smoke. This paper deals with the Safety Concept and the tunnel ventilation. A methodical approach was applied to prevent single critical scenarios being weighted too heavily in the design of the ventilation equipment. This achieved an optimisation of the entire system instead of designing the ventilation system for isolated extreme scenarios.
