Research on Discount Rate of CO and Smoke Baseline Emission in Road Tunnel Ventilation
It is known that calculating the required amount of air is the rationale of the whole design of road tunnel ventilation and defining the discount rate of CO and smoke baseline emission has also generates a great effect on the long-term required amount of air¡¤In terms of this, through listing and analyzing the components of vehicle pollutant discharge, emission standards of pollutants from cars in EU and discharge standards prescribed by PIARC, it turned out that the emission standards of vehicle pollutants in China should follow that of EU and should be divided into four stages.By analyzing the annual discount coefficient values and the standard emission discount of CO andrstrict limitation of the emission of CO and smoke from vehicles,development of automotive technology and domestic and overseas environmental requirements, it was suggested that at present the 1%~2% discount rate which set according to China¡¯sSpecificati for Design of Ventilation and Lighting of Highway Tunnel is conservative¡¤Therefore, a synthetic analysis should be made in real tunnel ventilatdesign and confining the required amount of air within a rational scope to ascertain the tunnel operation safety.
