突发情况下地铁站应急疏散研究

地铁车站作为城市轨道交通乘客集散的枢纽,其特殊、复杂的建筑结构和客流特性使得乘客在站内的安全问题尤其受到重视.如何预防和减少安全事故的发生,以及在突发事件情况下对乘客进行安全迅速的疏散,已经成为国内外研究的重要问题.本文在元胞自动机的基础上,考虑了突发情况下乘客存在的非理性行为,建立疏散模型,并利用Pathfinder仿真软件,对广州地铁1号线杨箕站进行模拟仿真,通过对仿真结果的分析,提出合理可行的意见和建议.

Research on Passenger Evacuation in a Subway Station under Emergency Situation

Subway station as the passenger distribution hub for urban rail transit, the special and complex structure and the characteristics of passenger flow of subway stations leads to the emphasis on passengers＇ safety in the stations. It has become a significant problem for both domestic and foreign researchers to study how to prevent and reduce the safety accidents and how to organize safe and rapid evacuation for passengers in emergency. In this paper, considering the existence of passengers＇ irrationality behavior under the emergency, evacuation model was established basis on the cellular automaton, and use the Pathfinder simulation software to simulate the Yangji station in Guangzhou Subway Line 1, through the analysis of simulation results, feasible suggestions and opinions was put forward.
