摘要
为了使中庭式地铁车站的排烟效率更高、消防设计更安全,研究了不同补风方式对排烟效率的影响。采用数值模拟方法,对中庭式地铁车站采用自然补风、站厅或站台机械补风等几种不同补风方式对排烟效率的影响进行分析,并分析了不同补风量对排烟效率的影响。研究表明:当站厅机械排烟量一定时,采用站台机械补风的方式排烟效率最高;机械补风条件下,补风量为排烟量的30%~50%时,能够达到最好的排烟效果。
In order to make the smoke exhausting efficiency of the atrium subway station higher, the influence of different air make-up ways was studied. In this paper, the numerical simulation analysis method is used to analyze the influence of different air make-up ways and volumes on the smoke exhausting efficiency under different scenarios as natural air supplement and mechanical air supplement in station hall or platform. The research shows that when the smoke exhausting volume in station hall is certain, the smoke exhausting efficiency is the highest by using the platform mechanical air make-up. And when the air supplement volume is between 30% and 50%, the best smoke exhausting effect can be achieved.
