深埋地铁隧道通风设计计算

Design of Ventilation in Deep Buried Metro Tunnel

通过设置合理的边界条件和参数,运用隧道环境模拟计算程序,对广州地铁6号线的隧道通风设计进行计算,并针对隧道内温度和风量进行了分析。在合理配置隧道通风系统的情况下,深埋隧道内全线温度满足要求;活塞效应作用较大,且隧道区间换气量满足要求。

Metro station is usually deep buried, so natural wind is hard to flow into the tunnel. Through setting logical houndary line and parameters, SES program is used to calculate the temperature and wind volume of the metro line. Under the circumstance that a suitable tunnel ventilation system is designed, the temperature in the whole tunnel will meet the requirements of the criterion; the piston compressor＇ s work will be more efficient and the air change volume in the tunnel will also meet the standards. The author holds that this design is a good example of metro tunnel ventilating for the future.
