武汉地铁交叉渡线处活塞风井设置研究

文章利用数值分析软件对武汉某地铁隧道的交叉渡线处的活塞风井设置进行了专题研究。该地铁交叉渡线长达300多米,该区域气流组织较复杂,且此处活塞风井的设置需兼顾通风、排烟和投资的需求。研究结果表明:在车站站台与交叉渡线之间设置活塞风井并适当增大风井面积,可满足温度和通风要求。

Study on piston air shaft setting in scissors crossover of Wuhan Metro

This paper using numerical analysis software on the subway tunnel crossover at the piston air shaft set do a thematic studies Subway crossing the line more than 300 meters long.The regional air current organization is complex,and here the Settings of the piston air shaft to give consideration to the ventilation and discharge smoke and investment demand.Study result shows that the piston shaft arranged on the station platform and crossover between,and appropriate to expand in area,and can meet the temperature and ventilation requirements.
