| 对故宫博物院燕喜堂的建筑特性和固定火灾荷载进行了详尽分析,运用FDS软件模拟多种火灾情景,系统整理和分析了火场的关键数据。研究揭示,燕喜堂的固定火灾荷载高达3 493.16 MJ· m-2,超出了现代建筑的平均水平;火灾发展至轰燃阶段的时间较短,屋顶区域面临的火灾风险尤为显著。在各种模拟情景下,燕喜堂室内2 m高度处的温度迅速超过了人体的安全耐受极限,同时,有毒气体CO和CO2的浓度也呈现出潜在威胁。随着烟雾的扩散和浓度的增加,人员疏散和文物抢救的难度显著提高。基于这些研究结果,并结合实际的工作需求,提出了具有针对性的防火建议,旨在为燕喜堂及类似的古建筑防火工作提供科学指导,以期提升其消防管理的科学性和有效性。 |

| A detailed analysis was conducted on the architectural characteristics and fixed fire loads of the Yanxi Hall in the Palace Museum. Using FDS software, various fire scenarios were simulated, and the key data from the fire scenes were systematically organized and analyzed. The study reveals that the fixed fire load of Yanxi Hall is as high as 3 493.16 MJ·m-2, exceeding the average level of modern buildings; the time required for the fire to develop to the flashover stage is relatively short, and the fire risk in the roof area is particularly significant. Under various simulated scenarios, the indoor temperature at a height of 2 meters in Yanxi Hall quickly exceeded the safe tolerance limit for the human body, and at the same time, the concentrations of toxic gases CO and CO2 posed potential threats. With the spread and increase in concentration of smoke, the difficulty of personnel evacuation and cultural relic rescue significantly increased. Based on these research results and in line with actual work needs, this paper proposes targeted fire prevention recommendations to provide scientific guidance for fire prevention work in Yanxi Hall and similar ancient buildings, thereby enhancing the effective and scientific management of fire. |
