【摘要】：影剧院这类的娱乐场所是典型的人员密集场所,在营业时通常处于人员高度密集的状态,一旦发生危害性事故,人员伤亡的概率是极高的,因此影剧院的安全问题一直是人们关注的焦点。然而,由于事故的发生及发展都具有明显的随机性,事故预防及人为干预的作用是十分有限的,因此,事故中人员疏散的可靠性就显得尤为重要。本文对影剧院建筑的人员疏散问题进行了研究。通过对影剧院人员疏散的具体过程的分析,绘制出影剧院人员安全疏散事件树,并结合轨迹交叉法分析出影剧院人员安全疏散的风险因素,找到安全疏散治理工作的重点所在。应用模糊综合评价法对影剧院的人员疏散性能进行了客观的安全评估,并应用熵权法与层次分析法相结合的方法对安全疏散评价中的各个指标进行了客观的分析,确定该影剧院的人员安全疏散水平,找到了人员安全疏散的薄弱环节所在,为模糊评价中的指标分析提供了更加科学的依据。最后根据某商场小型影剧院实际案例,应用FDS数值模拟的方法,模拟分析不同场景、不同时间的影剧院火场状态,科学地求出影剧院的可用安全疏散时间,找到影响该影剧院人员安全疏散的问题所在,为同类影剧院安全疏散提供理论依据。
[Abstract]:Entertainment places such as movie theaters are typically densely staffed, usually in a highly densely staffed state when they are open. In the event of a hazardous accident, the probability of casualties is extremely high. Therefore, the safety of the theater has been the focus of attention. However, the occurrence and development of accidents have obvious randomness, the role of accident prevention and human intervention is very limited, therefore, the reliability of evacuation is particularly important. This paper studies the evacuation of the cinema building. Through the analysis of the concrete process of the evacuation of the personnel of the film theater, the event tree of the safe evacuation of the personnel of the film theatre is drawn, and the risk factors of the safe evacuation of the personnel in the theatre are analyzed with the method of track crossing, and the key points of the management of the safe evacuation are found. The fuzzy comprehensive evaluation method is used to evaluate the evacuation performance of the theater, and the entropy weight method and the analytic hierarchy process method are used to analyze each index of the safety evacuation evaluation objectively. The safety evacuation level of the theatre is determined, the weak link of the safe evacuation is found, which provides a more scientific basis for the index analysis in the fuzzy evaluation. Finally, according to the actual case of a small film theater in a shopping mall, using the method of FDS numerical simulation, this paper simulates and analyzes the fire situation of the theater with different scenes and different times, and scientifically calculates the usable safe evacuation time of the theater. To find out the problems affecting the safe evacuation of the theater personnel, and provide the theoretical basis for the similar film theater safe evacuation.
