为解决特长城市复杂隧道通风系统因计算复杂而导致的运营规划困难、验证初始理想运营设计方案是否可靠等问题，针对某特长城市复杂隧道，采用SES通风软件，对南北线隧道在不同运营工况下的通风量进行模拟计算。计算比较不同车速工况下隧道风机总装机功率和洞口排污比例，确定隧道轴流风机和射流风机的开启位置和开启数量；分析阻滞工况下隧道内部和出口的污染物体积分数情况，验证优化方案的可行性。经研究发现： 车辆行驶产生的活塞风不能满足特长城市复杂隧道正常运营需风量的需求，需开启部分射流风机； 离隧道主线出入口过近的排风井排污效果较差，开启后会增大隧道通风能耗。

The operational planning of ventilation system of urban complex extralong tunnel is difficult due to its complex calculation. Hence, the ventilation volume of north line tunnel and south line tunnel under different operating conditions of an urban complex extralong tunnel is simulated and calculated by ventilation software SES to verify the reliability of initial ideal operation design. And then the total installed power of tunnel fan and discharge ratio of tunnel outlet under different vehicle speed conditions are calculated and put into comparison to determine the opening positions and quantity of tunnel axial fan and jet fan. Finally, the concentrations of pollutants inside and outside the tunnel are analyzed to verify the feasibility of the optimized scheme. The results show that: (1) The piston wind generated by traffic cannot meet the needs of air volume for the normal operation of the complex tunnels, and some jet fans need to be turned on. (2) The drainage effect of shafts close to the main entrance/exit of the tunnel is poor, and the ventilation energy consumption of the tunnel will be increased after opening the shafts.
