摘要
通过我国隧道通风规范与PIARC 2004对需风量计算比较,说明我国规范对污染物设计浓度、城市公路隧道需风量计算中存在差距。通过计算推导,认为我国规范中有关车密度系数取值有误,CO需风量无需气压、气温修正的结论。
By comparison of fresh air requirement calculation based on domestic specifications with that on PIARC2004, it is pointed out that there are gaps exist on pollutant design concentration and fresh air requirement calculation of urban road tunnel. Through formulae calculation, it is concluded that there are problems on values of vehicle density factor, as well as the problem on air pressure and air temperature modification for CO fresh air requirement.
