DEVELOPMENT OF NEW DESIGN PRINCIPLES FOR THE VENTILATION OF ROAD TUNNELS

ERMITTLUNG NEUER BEMESSUNGSGRUNDLAGEN FUER DIE LUEFTUNG VON STRASSENTUNNELS

DESIGN PRINCIPLES USED HITHERTO FOR THE VENTILATION OF ROAD TUNNELS (1 LORRY = 3 CARS) REQUIRE DETAILED STUDY ON THE BASIS OF LESS 00 PRODUCTION OF THE VEHICLES. FOR THE EFFICIENCY OF THE FRESH AIR CONDUCTED INTO THE TRAFFIC SPACE IMPORTANCE IS ATTACHED TO THE POSITION OF THE EQUIPMENT WHICH BLOWS IN THE AIR, AND ITS SPACING AND SIZE, AND ALSO TO THE EXTENT TO WHICH AND WHERE THE USED AIR IS SUCKED OUT. ASSUMED VALUES ONLY ARE AVAILABLE FOR PERMITTED CO LIMIT VALUES; NOTHING DEFINITE HAS BEEN ESTABLISHED ON DISTURBED VISION. THE RESULT OF THE RESEARCH PROJECT SHOULD PROVIDE FUTURE PLANNERS IN AUSTRIA WITH A UNIFORM BASIS FOR THE CALCULATION OF THE VENTILATION OF ROAD TUNNELS. MOREOVER COLLECTIVE RESULTS OF CURRENT RESEARCH INTO DETAILED QUESTIONS OF TUNNEL VENTILATION IS TO BE CONSIDERED AND PROCESSED.
