【摘要】 机场航站楼公共区存在较大的火灾危险性,并且公共区中各类可燃荷载的燃烧特点也不同。本研究通过对商铺货架、书店书架、值机普通座和商务桌椅开展全尺寸实体试验,并采用火灾模拟软件FDS进行全尺寸建模和数值模拟,分析荷载类型与燃烧过程和温度的相关性,对比实体试验与FDS模拟的燃烧过程、温度、HRR等参数的差异及原因,并通过SPSS技术分析差异的产生机理。研究结果表明,可燃物的HRR与O₂/CO₂释放率会降低实体试验的实测温度,数值比模拟温度低了16.67%～50%。荷载类型会影响实体试验的HRR和温度,而实测和模拟温度均与燃烧过程的HRR呈显著正相关性,O₂/CO₂释放率也会影响HRR和温度。FDS模拟过程应重点考虑各类可燃物的O₂/CO₂释放率,并减少SPR的比重,以提高模拟的准确度。本研究为航站楼多功能公共区的消防安全评估提供了理论依据和数据支撑。更多还原

【Abstract】 There is a high degree of fire risk in the public area of airport terminal,and the burning characteristics of various combustible loads in the public area are different.In this study,store shelves and bookstore shelves of goods,check-in and ordinary business entities tables and chairs.This study based on store and bookstore shelves,ordinary and business chairs were chosen as the research object,and both the full-size real test and fire simulation software FDS were applied,of which the effect of load type on combustion process and temperature was analyzed.The difference between real test and FDS simulation of combustion process was studied,and the factors of temperature and HRR were explore,and the underlying mechanism was analyzed by SPSS technology.The results showed that both HRR and O₂/CO₂ release rate could reduce the temperature of real test,resulted in a 16.67%～50% lower than the simulated temperature.The load type could obviously affect HRR and temperature of real test,and both the real and simulated temperatures show a significant positive correlation with the HRR of the combustion process,while the O₂/CO₂ release rate could in turns affect HRR and temperature.In order to improve accuracy of fire simulation,temperature,smoke diffusion and HRR,the O₂/CO₂ release rate of various combusted should be considered in FDS simulation process,and the proportion of SPR could be reduced.This study could provide theoretical basis and data support for fire safety assessment of multifunctional public area in airport terminal.更多还原
