【摘要】 近二十年来汽车生产制造技术和道(公)路隧道形式发生了巨大变化,隧道通风理念的发展理应与交通发展相适应,才能更好地为交通服务。分析了汽车尾气排放、隧道形式、城市交通等与通风密切相关的交通要素发展演变情况,结合隧道运行实际污染物水平,提出以CO为代表的污染物计算分析和监控在现今隧道建设和运行中的实际意义,以及交通发展给城市隧道洞口污染物排放方式带来的机遇。更多还原

【Abstract】 Great changes have taken place in automobile manufacturing technology and tunnel construction in the past 20 years. Only if the tunnel ventilation is adapted to the development of traffic, it could provide a good serivce for transportation. This paper analyses the development and evolution of traffic factors closely related to ventilation in the past 20 years, such as automobile exhaust emission, tunnel dimension and exit arrangment and urban traffic. Combined with the actural level of pollutants in tunnel operation, it concludes that the calculation, analysis and monitoring of CO-represented pollutants are practically significant in tunnel construction and operation and the traffic development has changed the pollutant portal discharge modes of urban tunnel.更多还原
