Paper Title:
Study on Fresh Air Demand of a Long Highway Tunnel
  Abstract

On the basis of a long highway tunnel, this paper has worked out different fresh air demands in tunnel under various conditions—different driving speed; renewal of vehicles; different combination of motor vehicle emission standards; emission of NOx considered or not considered. From three aspects (calculation methodology, exhaust emission, design concentrations of pollutants) this paper has made a comparative analysis between the results calculated according to JTJ026.1-1999 and PIARC2007. The research findings show that there still exists a huge gap between JTJ026.1-1999 and PIARC2007. Domestic specifications should be adjusted and improved in terms of exhaust emissions and design concentrations of pollutants, so as to achieve the purpose of determining reasonable fresh air demand.
