摘要: 为研究复杂城市地下互通各匝道及主线的风量及污染物分布情况,确定运营通风模式下工作井送排风机开启工况及射流风机配置情况,采用基于网络通风算法的IDA RTV软件模拟计算不同交通工况下隧道内污染物及风量分配情况,确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13排的送排风机工况,此时竖井排污比例为65%

Abstract: To clarify the air volume and pollutant distribution of each ramp and main line of underground interchange in complex urban areas, and determine the operating condition of the exhaust fan and the configuration of the jet fan in the working shaft under the operation ventilation mode, the network ventilation algorithmbased IDA RTV software is used to simulate and calculate the distribution of pollutants and air volume in the tunnel under different traffic conditions. The fan configuration under different traffic conditions is determined. Meanwhile, the proportion of pollutant discharge in the shaft under different combined conditions is simulated and the optimal combined conditions are determined. The results show that: (1) when the national standard is used to calculate the pollutant emission of vehicles, the traffic wind can meet the requirements of the tunnel air volume under the current traffic volume and the operating conditions without jet fan; (2) a certain number of jet fans need to be opened under blocking conditions. In the case of wind exhaust of the southern route, it is recommended to adopt the mode of one air supply fan and three air exhausters.  In this case, the pollutant discharge ratio of the vertical shaft is 65%.
