现代化的地铁车站出于乘客安全的考虑,屏蔽门系统被越来越多的引入。但是,屏蔽门系统对气流有较大的扰动,会对烟气流动规律产生一定影响,因此带屏蔽门系统的地铁车站沿用老式地铁车站的排烟应急模式势必存在一些问题。以地铁车站站台层公共区火灾为研究基础,运用理论分析和数值模拟相结合的方法,对带屏蔽门系统地铁车站烟气蔓延规律进行分析,对不同排烟方案进行对比,找出相对优势的排烟模式,希望对实际工程提供实用参考和宝贵建议。
Modern subway station for passenger safety considerations, screen door system is more and more introduced. However, the screen door system has a greater disturbance to the air flow, which will have some influence on the flue gas flow law. Therefore, the subway station with a screen door system will inevitably have some problems in using the smoke emergency mode of the old metro station. Based on the study of the fire in the public area of metro station platform and the combination of theoretical analysis and numerical simulation, this paper analyzes the law of smoke spread in metro station with screen door system and compares the different smoke evacuation schemes to find the relative advantages Exhaust mode, hoping to provide practical reference and valuable suggestions for practical projects.
