摘要
为研究地下批发商场的火灾危险性,选取某地下批发商场为研究对象,通过实地数据调查,设定3种典型火灾场景,包括商铺火灾、楼梯间火灾、走道火灾。利用FDS建立火灾模型,分析该地下批发商城的烟气流动情况,并根据火灾危险标准判定不同区域危险时间。以此为依据,利用Pathfinder疏散软件进行人员疏散模拟。结果表明,发生火灾时,该地下批发商城人员无法安全疏散,结合商场现状与模拟情况,通过对安全隐患整改,确保火灾情况下人员安全疏散,以此提出火灾防控措施。
In order to study the fire risk of underground wholesale shopping malls,an underground wholesale shopping mall was selected as the research object.Through the investigation of the field data,three typical fire scenarios were set,including shop fire,stairwell fire and walkway fire.The fire model was established by FDS,and the smoke flow in the underground wholesale mall was analyzed.According to the fire risk standard,the dangerous time in different areas was determined.Based on this,the evacuation simulation was carried out by Pathfinder evacuation software.The results showed that people in the underground wholesale mall can't evacuate safely in case of fire.Combined with the present situation and simulation situation of the mall,the safety hazard is rectified to ensure the safe evacuation of people in case of fire,and the fire prevention and control measures are put forward.
