【摘要】：随着20 km以上的长大铁路隧道及隧道群数量的不断增加,其防灾救援问题日益引起人们的关注。为获得长大铁路隧道及隧道群救援设施的规划方案,在对国内外长大铁路隧道及隧道群进行大量调研的基础上,按列车停车安全距离、火源长度和火灾烟气影响范围将铁路隧道群进行了细化。定义相邻隧道洞口间距小于250 m的铁路隧道为毗邻铁路隧道群,其紧急救援站设置主要考虑隧道内的紧急疏散通道、排烟、站台的加宽和洞口段的扩大;相邻隧道洞口间距在250~400 m的铁路隧道为连续隧道群,不设置紧急救援站;相邻隧道洞口间距大于400 m的铁路隧道为单体铁路隧道,其紧急救援站设置考虑横通道设置和洞内排烟模式。
[Abstract]:With the increasing of the number of long and long railway tunnels and tunnels more than 20 km, the disaster prevention and rescue problem has attracted more and more attention. In order to obtain the plan of rescue facilities for long and long railway tunnels and tunnels, the problem of disaster prevention and rescue is becoming more and more important. On the basis of a large number of investigations on domestic and foreign long railway tunnels and tunnel groups, according to the safe distance of train stopping, The length of fire source and the influence range of fire smoke refine the railway tunnel group. The railway tunnel with adjacent tunnel opening space less than 250m is defined as the adjacent railway tunnel group. The emergency rescue station mainly considers the emergency evacuation passage in the tunnel. Exhaust smoke, widening of platform and expansion of opening section; Railway tunnels with adjacent tunnel opening spacing of 250 ~ 400m are continuous tunnel groups, and no emergency rescue stations are set up; railway tunnels with adjacent tunnels spacing more than 400m are single railway tunnels. The emergency rescue station setting takes into account the horizontal passage setting and the smoke exhaust mode in the hole.
