摘　　要：公路隧道污染物折减率是计算隧道需风量的关键参数。从我国机动车污染物排放标准及PIARC 2012标准中分析了公路隧道污染物折减率的变化过程,并依托实际工程说明了公路隧道污染物折减率取值对特长隧道工程投资的影响。The pollutant reduction rate of highway tunnel is the key parameter to calculate the tunnel air demand.This paper analyzes the changing process of the reduction rate of pollutants in highway tunnels from the emission standard of motor vehicles in our country and the standard of PIARC 2012,based on the actual project,the influence of the pollutant reduction rate of highway tunnel on the investment of extra-long tunnel project is explained.

关 键 词：公路隧道 污染物折减率 PIARC 需风量
