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.
With space syntax, the space of single-track and three-rail stations is researched. Considering the variables of convenience of spatial analysis variables, the characteristics of flow lines in stations, the conflict points of streamlines and pedestrian perception, the safety zone of rail station fires is defined The paper points out that the evacuation course should be divided into two stages when the fire or other accident at the station platform of the railway station evacuates, and the requirements of evacuation time should be separately stipulated in each stage so as to provide suggestions for the future revision and improvement of the relevant regulations on emergency evacuation of Subway Design Code.
