某地铁车站公共区热烟试验及排烟系统方案优化浅析

Rail Substation Ventilation Analysis and Comparison

地铁车站防排烟系统实施过程中受制于施工难度、设计施工周期、设计施工技术水平、及运营管理水平等因素的影响,火灾发生时,如何有效、可靠的发挥其功能存在较多的不确定性。鉴于此,在地铁车站采用热烟试验的方式,模拟火灾发生时烟气流动规律,检验防排烟控制系统的可靠性、优化排烟系统设计方案、验证排烟效果是一种简单,可靠,切实可行的方式。

During the implementation of smoke exhaust system in subway stations,the construction difficulty,design and construction period,design and construction technology level,operation and management level,etc.There are many uncertainties about how to play its function effectively and reliably.In view of this,it is a simple and reliable way to test the reliability of the smoke exhaust system,optimize the design scheme of the smoke extraction system,and verify the smoke extraction effect by means of smoke test in the subway station to simulate the smoke flow law in case of fire,in a practical way.
