定不同交通工况下的风机配置情况,同时针对不同送排组合工况下的竖井排污比例进行模拟计算确定了最佳组合工况。结果

表明:采用国Ⅳ标准计算车辆污染物排放,运营工况下,隧道内无需开启射流风机,现有交通量情况下交通风即可满足隧道

风量要求,阻滞工况下需要开启一定数量的射流风机。南线送排方案情况下,南线隧道建议采用 1 送 3 排的送排风机工况,

此时竖井排污比例为 65%。

Abstract: In order to study the distribution of air volume and pollutant in each ramp of Underground Interchange and

determine the operation state of supply fan, exhaust fan and jet fan. IDA RTV software, which is based on network

ventilation algorithm, was adopted to simulate the distribution of pollutants and air volume in the tunnel under

different traffic conditions. At the same time, simulation calculation is carried out to determine the optimal fan

operation state according to the shaft sewage ratio. The results show that: using Euro IV standard to calculate vehicle

pollutant emissions, there is no need to turn on jet fans in the tunnel under operation state, the traffic air can meet

the air quality requirements; and a certain number of jet fans need to be turned on under the traffic congestion. The
