某大型商业综合体火灾模拟及人员疏散研究

Study on Fire Simulation and Evacuation of a Large-scale Commercial Complex

为降低大型商业综合体火灾的危害性,并保障人员安全疏散,本文以某大型商业综合体为研究对象,采用PyroSim和Pathfinder软件对其6个火灾场景进行火灾烟气蔓延和人员疏散模拟,研究不同火灾场景下的必需安全疏散时间和可用安全时间。结果表明:在设定的火灾场景下,人员能够疏散至安全区域;当自动喷水灭火系统和防火卷帘均失效时,着火区域人员疏散存在风险。

In order to reduce the fire hazards of large-scale commercial complexes and ensure the occupant's safety evacuation,in this paper,a large-scale commercial complex was taken as the research object,and PyroSim and Pathfinder software were used to simulate the spread of fire smoke and the occupant's evacuation under six fire scenarios.Required safe evacuation time(T_(RSET))and available safe evacuation time(T_(ASET))under different fire scenarios were studied.The results show that occupants can be evacuated to a safe area under the given fire scenarios;and that when both the sprinkler system and the fire-resistant shutter fail,there is a risk of occupant's evacuation in the fire area.
