以某大型综合体购物中心的共享空间为例,通过火灾危险性因素分析,运用FDS模拟火灾烟气蔓延状态,分析了火灾烟气的危险性及对人员疏散的影响。以共享空间现实业态的使用状态为火灾场景设置条件,分析评估了该区域的火灾危险性,并结合模拟结论提出了消防安全对策及建议。 Taking the shared space of a large complex shopping center as an example, this paper analyzes the risk of fire smoke and the influence on fire evacuation by analyzing the fire risk factors and using FDS to simulate the fire smoke spread status. Based on the use status of the real world in the shared space, the conditions for the fire scene were set, the fire risk in the area was analyzed and evaluated, and the fire safety measures and suggestions were put forward based on the simulation results.
