轨道站火灾疏散安全区域界定研究

Study on Safe Area in Railway Station Under Fire

摘要:

借助空间句法对单线和三线轨道车站的空间进行研究，综合考虑空间形态分析变量便捷度指标、站内人流动线的特征、流线冲突点、行人感知等因素，界定轨道站火灾情况下的安全区域.指出轨道站站台发生火灾等事故时疏散过程应分为两个阶段，每个阶段应分别规定疏散时间要求，为日后《地铁设计规范》紧急疏散部分相关规定的修订与完善提供建议.

Abstract:

An analysis was made of the space of the different types of railway stations in Shanghai by means of the space syntax with a consideration of the space integration value,the characteristics and conflict point of streamlines as well as the apperception of the pedestrian.Then the safe area from fire was determined,and the railway station platform evacuation procedure was proposed to be divided into two stages when an accident such as a fire happened,and each stage should be provided separately evacuation time requirements.These proposals are helpful for a future amending and perfecting of“Railway Design Manual”on emergency evacuation.
