摘要
研究目的:紧急救援站防灾通风系统设计是特长铁路隧道防灾系统设计的一个关键问题,合理优化的防灾通风系统直接关系着灾害时人员的安全疏散。本文采用网络通风计算方法,主要对单洞单线隧道平导救援站内防灾通风系统进行优化研究,并考虑自然风对紧急救援站风流分布的影响,从而确定合理的防灾通风系统。研究结论:(1)提出了一种适用于平导救援站的优化防灾通风系统方案;(2)探明了自然风对紧急救援站联络横通道内风速分布的影响规律,建议对隧道内自然风进行长期监测,并在紧急救援站两端增加布置一定数量的射流风机;(3)该研究结果可对特长铁路隧道防灾救援系统的设计提供指导。
Research purposes： The design of the disaster ventilation system in the emergency rescue station is a key point for the disaster prevention system in extra -long railway tunnel. A reasonable and optimized disaster ventilation system is the basis for evacuation in the case of disaster. This paper is aimed to study the optimization of the disaster ventilation system in the parallel pilot hole emergency rescue station of single hole single line tunnel. Research conclusions： （1） Proposing an optimized ventilation system for the parallel pilot hole emergency rescue station. （2） Understanding the effect of the natural wind on the velocity distribution of the pedestrian crosswalk. A long term monitor of the natural velocity is suggested in a tunnel, as well as a number of the jet fans at both ends of the emergency rescue station are increased. （3） The results would be useful for the design of the disaster prevention system in extra- long railway tunnel.
