地铁车站排烟系统优化研究

Study on the Optimization of the Exhaust System at Subway Stations

本文结合无锡地铁某一标准站,通过车站站台、站厅两种火灾工况,测试了车站扶梯位置的流速、烟气的控制效果、设备的联动情况,分析在不同工况下的各系统动作模式。通过站台两侧测试对比分析,对车站的排烟动作模式进行了优化,有效地提高了系统的排烟效果。

This paper combines with a standard station of Wuxi metro, tests the flow rate of station ladder, smoke control effect and equipment linkage under two scenarios of fire at the station platform and station hall, and analyzes the system action mode under different operating conditions. Through the comparative analysis on two sides of the platform, the smoke exhaust action mode of the station is optimized, which effectively improves the smoke emission effect of the system.
