摘要
分析城市轨道交通联通型地下空间火灾的特点及人员疏散过程中的心理特征、行走速度、人员密度、流动系数等。设定疏散场景,采用BuildingEXODUS软件分析人员疏散过程,评价消防设计的有效性。针对疏散瓶颈,提出将主要疏散出口由2.8m增加至4.0m,缩短疏散时间,保障人员安全。
The fire characteristics of unicom type of underground space in urban rail transit were analyzed,and mental characteristics,walking speed,crowd density and flow coefficient were also discussed.Evacuation scenario was set by BuildingEXODUS to evaluate the effectiveness of fire protection design.In view of the evacuation bottleneck,measure of increasing the width of evacuation exit from 2.8 m to 4.0 m was proposed to shorten evacuation time.
