摘要
随着我国城市轨道交通的发展,地铁深埋站点将越来越多。深埋地铁站点及区间隧道消防安全是深埋车站设计过程中需要加以考虑的科学问题,本文主要介绍深埋地铁车站站台火灾模型实验过程,分析火源功率为2．5MW的站台火灾过程中,烟气在站台内的蔓延过程、站台内气流组织情况、站台烟气向邻近空间蔓延的特点;探讨深埋车站烟气蔓延和控制规律,为深埋站点的火灾安全设计提供参考。
With the development of inter city rail transit in China, more and more deep buried metro stations （DBMS） will be built. The fire safety in these metro stations should be inspected much further. The paper mainly reports the burning tests of platform fires of 2.5MW performed in the DBMS model. By the experimental result, the smoke spread process in the platform and air flow pattern are studied, based on which the efficient fire control precepts are analyzes, the research results are useful for the ventilation design in DBMS.
