【摘要】 北京地铁1、2号线由于修建年代较早,防排烟系统与消防设施配备等方面不够完善,需要进行防灾研究。本文通过对北京地铁1、2号线典型车站进行现场调研与试验测试,分析通风防排烟系统现状,找出不符合规范以及需要改进的地方,依据现状评估提出可行的改造建议,利用CFD数值模拟验证改造建议的可行性和考察改造效果,最终达到改造车站防排烟系统使之满足安全要求的目的。更多还原

【Abstract】 Due to the faultiness of smoke management system and fire protection in Beijing subway line 1 and 2,the disaster prevention need to be studied.The paper analyses the actuality of ventilation and smoke management system by an on-site invcstigation and experimental test of a typical station and find out some inconsistent with the norms and improvement needed.The feasibility of alteration, according to assessment of the status,was validated by CFD simulation.Ultimately,it meets the requirements for safety for smoke control system of alteration station.更多还原
