Koralm Tunnel
KORALM TUNNEL – DEVELOPMENT OF TUNNEL SYSTEM DESIGN AND SAFETY CONCEPT Christof Neumann, Florian Diernhofer, ILF Consulting Engineers, Austria Gerhard Harer, Josef Koinig, OEBB Infrastruktur Bau AG 1 ABSTRACT The 32.8-km-long Koralm tunnel requires additional measures to guarantee a sufficient safety level. The methodology applied to define safety measures for this very long tunnel is on the one hand based on a set of guidelines and on the other hand based on the specific boundary conditions of this tunnel. These tunnel-specific conditions are considered by establishing customized safety targets. As a result of an investigation into the construction and operating phase, the tunnel system was determined to consist of two single-tube tunnels, an emergency station, no crossover and cross- passages every 500 m. The emergency station in the centre of the tunnel, which incorporates various considerations, was designed to accommodate staggered platforms and a refuge room with a length of 800 m. With a view to the incident management strategy to be adopted, characteristic operating scenarios were analysed to realistically reflect the sequence of events in case of an emergency. 2 THE KORALM TUNNEL PROJECT The Koralm tunnel is one of the key elements of the Koralm high-capacity railway line, which connects the cities of Graz and Klagenfurt in the south of Austria. The Koralm railway line is part of the Baltic-Adriatic Axis, which represents the easternmost crossing of the Alps and links several Eastern European countries Koralm line with Koralm tunnel and Vienna with southern Austria and northern Italy. The Koralm line is a 130- km-long high-capacity railway line engineered for a design speed of 200 km/h. -

New Emission Data for Ventilation Design for Road Tunnels
- 1 - DUST LOADS IN RAILWAY TUNNELS – RESULTS FROM IN-SITU MEASUREMENTS AND CONSEQUENCES FOR TUNNEL FACILITIES AND RAILWAY OPERATION 1Helmut Steiner, 2Peter Sturm, 2Daniel Fruhwirt, 1ÖBB Infrastruktur AG, A; 2Graz University of Technology, A ABSTRACT Several long railway tunnels are currently under construction in Austria (e.g. the Koralm Tunnel / KAT; Semmering Base Tunnel / SBT; Brenner Base Tunnel / BBT). The project KAT is now at the beginning stage of implementation with respect to technical railway equipment. In order to complete the detailed planning several very specific topics have to be examined in detail. The ÖBB (Austrian railway corporation) has thus begun detailed research in the relevant areas in order to grapple with problems at their root, and to allow for findings to be incorporated into ongoing projects. For example, it is known from cases in Switzerland, where several long railway tunnels have been in operation for years (Lötschberg Base Tunnel / LBT; Gotthard Base Tunnel / GBT), that technical equipment needs a lot of maintenance when it is exposed to high dust loads. The quantity and composition of the dust also play a key role here. To assess the nature of the problem, in-situ measurements were thus carried out in an ÖBB railway tunnel under full operation in Upper Styria. The knowledge gained from these measurements is to be integrated into current and future rail tunnel projects. Specific attempts were made to derive characteristic emission factors in relation to different train types. It should then prove possible to estimate total dust emissions in current and future projects, depending on the specific operating programs, timetables, train mix etc. -

The methodology applied to define safety measures for this very long tunnel is on the one hand based on a set of guidelines and on the other hand based on the specific boundary conditions of this tunnel. These tunnel-specific conditions are considered by establishing customized safety targets. All aspects of safety are summarized in a specific tunnel safety concept. As a result of an investigation into the construction and operating phase, the tunnel system was determined to consist of two single-tube tunnels, an emergency station, cross-passages every 500 m and no crossover. The emergency station in the centre of the tunnel, which incorporates various considerations, was designed to accommodate staggered platforms and a combined refuge room with a length of 800 m. The physical structures of the emergency station (distance of escape tunnels, door configurations, etc.) were checked by application of an evacuation simulation. With a view to the incident management strategy to be adopted, characteristic operating scenarios were analysed to realistically reflect the sequence of events in case of an emergency.

Rescue, Evacuation and Fire Protection at the Koralm
- 21 - INCIDENT TESTED: RESCUE, EVACUATION AND FIRE PROTECTION AT THE KORALM TUNNEL 2 A REVIEW OF THE FIRE EVENT IN 2015 AND THE PRACTICAL IMPLEMENTATION OF THE CONCEPT IN THE EVENT OF AN INCIDENT S. Fehleisen, ÖBB-Infrastruktur AG J. Frießnegg; ARGE KAT2, Austria 1. ABSTRACT As a new high-speed railway connection between Graz and Klagenfurt, the Koralm Railway represents a crucial component in the context of the Baltic-Adriatic Corridor. With a length of about 33 kilometres, the Koralm Tunnel--the centrepiece of this new line--will become one of the longest traffic tunnel constructions in the world. In the tunnel construction phase, the construction lot “Koralm Tunnel 2” represents the longest of the three main construction lots. Apart from excavator driving and drill-and-blast driving, two tunnel boring machines are also being used on this 20 kilometre length. The length as well as the complexity already pose specific challenges for the construction phase in terms of safety, rescue and evacuation, and fire prevention. With the starting of the construction in 2011, the implementation of the rescue, evacuation and fire protection concept specified in the tender was also initiated by the contractor in cooperation with the client and the emergency services. In February 2015, the emergency management had to be put into real action on account of a fire in an standby generator on one of the two tunnel boring machines. The fire could be brought under control successfully and all persons were rescued and evacuated from the tunnel unharmed. The professional and calm handling of the incident showed how significant prior emergency drills and coordination are. -

AGRUFLEX™ Tunnel Liner Protects Koralm Tunnel from Ground Water
AGRUFLEX™ Tunnel Liner Protects Koralm Tunnel from Ground Water Scheduled to be operational in 2022, the Koralm Tunnel project, at 20 miles, will be Austria’s longest railway tunnel. The ambitious project is part of the Koralm Railway project, an 80 mile line that will link Graz with Klagenfurt. The new high speed line is expected to reduce travel time between the two cities from three hours to one. The Koralm Tunnel, which runs at depths of 4000 feet below the surface in the Koralpe mountain range, is comprised of two parallel tunnels, each with a single track, linked with crossways every 550 yards. Construction Challenges: The geomembrane used to seal the tunnel had to meet the strict 2012 Austrian Tunnel Sealing Guideline Koralm Tunnel, Austria (Österreichische Bautechnik Vereinigung or ÖBV). It also had to protect the new tunnel from groundwater. The Solution: Construction began in 2008 at the tunnel’s east entrance or the KAT 1, a section length totaling approximately 1.4 miles. To meet the ÖBV guideline and protect the tunnel from groundwater seepage, engineers chose 2.1 mm AGRUFLEX tunnel liner. Approximately 1,400,000 sq. ft. of the 80 mil. liner was installed between 2012 and 2013, along with an additional 40,000 feet of water stop profiles (AA 500/6.) The KAT 1 tunnel section was successfully completed in November 2013. Extensive testing has proven that the AGRUFLEX tunnel liner has met the ÖBV Guideline for chemical and water resistance and has minimal environmental impact.
