摘　　要：对上海城市隧道进行调研。以上海市外滩隧道通风井作为研究对象,通过交通工况调查和实测,总结通风井设计特点,对实测日正常交通工况、阻滞交通工况下北通风井承担隧道稀释CO需风量比例进行计算。纵向通风系统可提高隧道内空间利用率。与城市建筑相结合的设计方法,成为城市中心区隧道通风井的设计趋势。与城市建筑相结合的城市中心区隧道通风井,排放高度受周边建筑高度的限制,普遍低于非城市中心区的隧道通风井。在实测日,外滩隧道北通风井正常交通工况下可承担47.8%的通风量,阻滞交通工况下可承担23.9%的通风量。The investigation of Shanghai urban tunnels is carried out.Taking the ventilation shafts of the Bund Tunnel in Shanghai as the research object,through the investigation and actual measurement of traffic conditions,the design characteristics of the ventilation shafts are summarized,and the proportion of air volume required for the north ventilation shaft to bear the diluted CO in the tunnel under the normal traffic condition and blocked traffic condition on the measured daily is calculated.The longitudinal ventilation system can improve the utilization rate of space in the tunnel.The design method combined with urban architecture has become the design trend of tunnel ventilation shafts in urban central areas.The emission height of tunnel ventilation shafts in urban central areas combined with urban architecture is limited by the height of surrounding buildings,and is generally lower than that of tunnel ventilation shafts in non-urban central areas.On the measured daily,the north ventilation shaft of the Bund Tunnel can bear 47.8%of the ventilation volume under the normal traffic condition,and can bear 23.9%of the ventilation volume under the blocked traffic condition.
