摘　　要：利用全尺寸热烟测试(Hot SmokeTest)的方法,在一个四节编组、安全门系统制式下的地下二层地铁车站,开展了防灾系统安全性的火灾热烟测试实验,检测了地铁防灾系统的联动效果、事故模式切换状况和综合安全性能,实验得到了闭式全高安全门系统下的烟气扩散特点、楼扶梯开口向下流速、有效疏散时间,分析了排烟量的非对称性设计导致的烟气非对称流动特点。实验数据可为国内类似的采用四节编组(80m长)的站台、闭式系统设计的地铁线路提供参考。Using the method of full-scale hot smoke test, a fire test is performed on the safety of disaster prevention system in a metro station, which is a type of underground two-level island, four marshaling and safety door system. By the tests, the interconnection of the disaster prevention system, accidents mode switching condition and overall safety performance is examined. The data of smoke diffusion characteristics under high security doors system, the downward velocity in the escalator opening, the available safe evacuation time are obtained by experiments. The characteristic of the asymmetric smoke flow under asymmetric exhaust volume amount design is analyzed. The results of this article can be for reference of the disaster prevention system design for domestic metro line with fourmarshaling station of 80m long and closed system.
