摘要
医院建筑被认为是最具建设挑战性的建筑设施,在建设过程中存在诸多不确定性因素,例如人口趋势,疾病的变化模式,技术进步和临床知识等等。其中,遇到灾害现象的建筑安全性尤为重要,医院建筑的人员复杂性、密集化、可燃物众多等特点为其增加了火灾隐患,在发生火灾时,由于其不同人员的疏散条件差异性,导致其疏散的难度很高,所以对于医院建筑可能存在的消防隐患以及建立全面可靠的防火监督很有必要。本文详细说明了大型医院建筑火灾模拟及逃生分析的技术路线,包括模型构建、通风分析、火灾模拟和疏散分析等步骤,并以某大型医院为例进行模拟分析,得出最不利通风工况、火灾发生过程温度分布云图、烟气分布云图以及各房间疏散路线等结果,通过项目研究可以为类似项目的分析提供技术路线参考。
Hospital buildings are considered to be the most challenging building facilities,and there are many uncertainties in the construction process,such as population trends,disease patterns,technological advances and clinical knowledge. Among them,the safety of buildings in the event of disasters is particularly important. The complexity,density and flammable materials of hospital buildings add to the fire hazard. In the event of fire,due to the differences in evacuation conditions of different personnel,It is very difficult to evacuate,so it is necessary to have possible fire hazards in hospital buildings and to establish comprehensive and reliable fire supervision. This paper describes in detail the technical route of building fire simulation and escape analysis in large hospitals,including model construction,ventilation analysis,fire simulation and evacuation analysis. The simulation analysis is carried out by taking a large hospital as an example to obtain the most unfavorable ventilation conditions. The results of temperature distribution cloud map,smoke distribution cloud map and evacuation route of each room in the fire process can provide technical route reference for the analysis of similar projects through project research.
