摘要
本研究以城市地下道路为研究对象,结合理论分析与现场实测研究方法,重点分析影响城市地下道路通风系统稀释CO需风量关键因素及其变化规律;并以上海市延安东路隧道为例,通过隧道实测法对目前城市地下道路交通状况、机动车流综合平均CO排放因子等进行了综合分析;进一步给出了相应条件下该隧道通风系统稀释CO需风量,该值仅为按现行公路隧道相关规范计算值的35%。研究结果表明,城市地下道路通风系统设计计算不能简单照搬公路隧道的标准或规范。
This study aims at urban underground tunnel and analyzes key parameters of air volume flow necessary for CO dilution by theoretical analysis and field measurements. Measurements of traffic characteristics and vehicle emission characteristics were performed in Shanghai East Yan＇an Road Tunnel and average CO emission factors were calculated.And then, air volume flow necessary for CO dilution was calculated, which was 35% of the value of road tunnel. The result showed that urban underground tunnel ventilation system design can＇t simply refer to the standard or specification of road tunnel indiscriminately.
