ADVANCED TUNNEL VENTILATION SYSTEM FOR THE KARAWANKEN TUNNEL ---PAPERS PRESENTED AT THE 6TH INTERNATIONAL SYMPOSIUM ON THE AERODYNAMICS AND VENTILATION OF VEHICLE TUNNELS, DURHAM, 27-29 SEPT 1988

The present paper describes how significant economic improvements could be achieved for the karawanken tunnel by optimizing the ventilation system considering the effects of the latest emission situation and legislation. The 7864 M long single-tube motorway tunnel between Austria and Yugoslavia was originally planned in 1978 with a fully transverse ventilation system. In 1985, the whole concept was reconsidered mainly due to the changed situation in respect of vehicle emissions. During the optimization process all the expensive shafts and caverns could be eliminated. Finally, the new concept ended up in considerable total cost savings. In the paper, the effect of the decrease in vehicle emissions on the fresh air demand is presented. The original ventilation concept, as well as the new optimized concept, are described in detail. The karawanken tunnel will be the longest highly frequented motorway tunnel worldwide without any ventilation shafts or caverns.(a)
