摘　　要：采用数值模拟的方法对设双活塞风井的屏蔽门地铁系统的风井通风特性进行了研究,以活塞风井的风量和通风效率作为活塞风井通风特性的评价指标,主要分析了行车对数和风井与车站的距离对于活塞风井通风特性的影响,研究结果对于地铁环控系统设计具有参考意义。In this paper,a typical subway model using PSD system with double piston air shaft is established by SES software.Taking the ventilation volume and ventilation efficiency as the evaluation index of the ventilation performance of the piston shaft,the effects of train pairs and the distance between shaft and station on the ventilation performance of the piston shaft is analyzed.The results are of reference significance for the design of subway environment control system.

关 键 词：屏蔽门系统 双活塞风井 通风效率
