【摘要】：文章分析了各规范、标准对火灾发生时疏散和避难的有关规定,明确提出新的隧道群的定义。结合明线地形为桥、路堤、路堑及挡墙时的实际情况,对疏散通道和避难所的设置分别进行了科学的分析。解决了铁路总公司各部门、设计方、咨询方、地方和铁路消防部门面临的难题。得出结论如下:"隧道群"定义决定隧道内防灾救援工程的设置,隧道外防灾救援设施可突破或改变规范中"隧道群"定义。列车驶出隧道,停在明线疏散旅客时,现场设有满足相关规范和标准要求的疏散、避难设施,则不应视为隧道群。两相邻隧道间的明线无相关规范和标准要求的疏散、避难设施时,两隧道及明线的范围应视为隧道群,与明线的长度无关,即与隧道洞口间距无关。
[Abstract]:In this paper, the relevant regulations of evacuation and refuge in case of fire are analyzed, and a new definition of tunnel group is put forward. Combined with the actual situation of bridge, embankment, cutting and retaining wall, the setting of evacuation passage and shelter are analyzed scientifically. Solve the problems faced by railway company departments, designers, consultants, local and railway fire departments. The conclusions are as follows: the definition of "tunnel group" determines the installation of disaster prevention and rescue works in the tunnel, and the disaster prevention and rescue facilities outside the tunnel can break through or change the definition of "tunnel group" in the code. When the train leaves the tunnel and stops on the open line to evacuate passengers, there are evacuation facilities which meet the requirements of relevant codes and standards, and asylum facilities should not be regarded as tunnel groups. The open lines between the two adjacent tunnels are evacuated without the relevant codes and standards. In the case of refuge facilities, the scope of the two tunnels and the open lines should be regarded as a group of tunnels, independent of the length of the open lines, that is, the distance between the openings of the tunnels.
