哈尔滨秋林商厦的火灾和疏散模拟仿真研究

哈尔滨秋林商厦的火灾和疏散模拟仿真研究摘要随着中国城市化进程的加速，火灾安全问题愈发凸显其重要性。尽管预防和控制始终是减少火灾、保障人员生命财产安全的基石，但随着技术的进步，我们有了更多手段来研究和应对火灾。本文利用计算机仿真软件Pyrosim和Pathfinder,.对秋林公司的火灾发展和人员安全疏散进行了深入模拟和分析，希望能够为商业建筑火灾的研究提供有价值的参考。本文旨在深入探讨秋林公司建筑特性下的火灾风险，并基于火灾发生的原因、发展进程和蔓延规律，对秋林公司火灾发展的动态过程做出描述和分析。结合秋林公司内部商品的具体布局和实地调查数据，本文设计了针对性的火灾场景，并运用Pyrosim火灾模拟软件进行了模拟分析。模拟结果揭示了火灾中烟气的主导作用，以及其对人员安全疏散构成的威胁，特别是能见度因素对疏散效率具有显著影响。在Pyrosim模拟的基础上，本文进一步利用Pathfinder人员疏散软件对秋林公司人员疏散过程进行了详细模拟。关键词火灾仿真模拟：Pyrosim;人员疏散模拟：Pathfinder-1-Simulation study of fire and evacuation in Qiulinshopping building in HarbinAbstractWith the acceleration of China's urbanization process,the problem of firesafety has become more and more important.Although prevention and control isalways the cornerstone of reducing fire,and ensuring the safety of life andproperty of people,but with the progress of technology,we have more means tostudy and respond to fire.This paper uses the computer simulation softwarePyrosim and Pathfinder to deeply simulate and analyze the fire development andpersonnel safety evacuation of Qiulin Company,hoping to provide valuablereference for the study of commercial building fire.This paper aims to explore the fire risk under the building characteristics ofQiulin Company,and describe and analyze the dynamic process of firedevelopment of Qiulin Company based on the cause,development process andspread law of fire.Combined with the specific layout of Qiulin internal productsand field survey data,this paper designs targeted fire scenes,and uses Pyrosimfire simulation software for simulation analysis.The simulation results revealthe leading role of smoke in fire,and the threat to personnel safety evacuation,especially the visibility factors have a significant impact on the evacuationefficiency.On the basis of Pyrosim simulation,this paper further uses thePathfinder evacuation software.KeywordsFire Simulation,Pyrosim,Personnel Evacuation Simulation,Pathfinder目录摘要。..............Abstract....第1章绪论111.1课题背景1.2研究意义21.3国内外研究现状分析21.3.1国内研究现状21.3.2国外研究现状X1.4论文研究的主要内容5第2章相关方法理论及火灾危险性分析72.1火灾模拟理论72.2人员疏散理论72.3火灾危险性分析…2.3.1商场建筑特点分析82.3.2秋林公司商业建筑防火及安全疏散的影响因素102.4本章小结.11第3章火灾数值模拟123.1.1 Pyrosim火灾模拟软件123.2火灾场景设定.…133.2.1火灾场景设定的原则133.2.2确定火源及火灾场景位置设定133.2.3火灾规模设定133.2.4火灾场景参数设计143.2.5建立火灾物理模型143.3烟气模拟结果分析153.3.1火灾场景1.163.3.2火灾场景2.233.4本章小结30第4章人员疏散模拟314.1 Pathfinder疏散软件314.2疏散模拟分析的基本假定条件314.3人员疏散参数设置324.3.1疏散人员速度设置32-Ⅲ-4.3.2疏散路径设置324.4 Pathfinder模拟及结果分析334.5本章小结aaacaccccc--36结论37致谢。38参考文献…39附录A.41附录B…59附录C….72
