城市轨道交通盾构隧道疏散路径研究

Research on evacuation path of shield tunnel in urban rail transit

盾构隧道应急疏散是指城市轨道交通车辆在盾构隧道区间行驶中遇到火灾或其他灾害事故情况下迫停于隧道内,乘务人员引导乘客可控、高效地向安全区疏散的过程.文章阐述了目前盾构隧道区间应急疏散的模式及设计分歧,提出了不同疏散路径下最高效的疏散模式,以及区间疏散平台与联络通道的接口方案,为类似工况下的应急疏散提供参考.

Shield tunnel emergency evacuation refers to the process in which urban rail transit vehicles are forced to stop in the tunnel in case of fire or other disasters and accidents while driving in the shield tunnel section,and the crew guides passengers to evacuate to the safety area in a controllable and efficient manner.This paper introduces the current emergency evacuation mode and design differences of shield tunnel section,analyzes and puts forward the most efficient evacuation mode under different evacuation paths,and puts forward the interface scheme between the section evacuation platform and the connecting passage.This can provide reference for emergency evacuation under similar conditions.
