地铁区间活塞通风形式对比研究

Comparative Research on Piston Ventilation of Subway Tunnel

对相同地下区间隧道分别设置单塞井形式与双塞井形式,通过软件计算分析两种形式在区间隧道在通风效果上的差异,同时结合土建规模、设备运行要求等,分析不同行车密度、不同排热风机运行风量对两种活塞通风形式下区间通风效果的影响。

The single piston ventilation form and the double piston ventilation form were provided on the same underground tunnel in this article, the method of computer simulation is used to analysis the difference of the two forms in tunnel ventilation effect, Taking into account the construction scale, equipment operation requirements, the article analysis the affect about the different density, different exhaust fan operation flow to the ventilation effect in two kinds of piston ventilation form.
