【摘要】 针对汽车尾气排放量的大幅度下降、复杂隧道和城市交通常发拥堵的状况,分析了隧道通风日常和阻滞通风的主要目标和设计思路的转变,提出了污染物浓度控制已不是隧道通风的主要任务,并提出阻滞工况设计新思路、将交通仿真结合交通控制引入事故通风交通场景分析。更多还原

【Abstract】 At present the automobile exhaust emission is greatly reduced while traffic congestion often happens in complex tunnels and cities. So the main tasks and design concepts of tunnel ventilation in normal condition and in congested traffic have been changed. The pollutant concentration control has not been the main task of the tunnel ventilation. For tunnel in congested traffic scenario a new ventilation design concept is proposed. And the traffic simulation and control are introduced into the accident ventilation scenario analysis.更多还原
