摘要:随着社会的发展,世界科技的进步,人们的安全意识在不断增强,文护生命和财产安全引起了全社会的广泛关注。然而,国内外每天频频传来公共聚集场所安全事故的新闻,因而公共场所的安全疏散问题也逐渐被人们所重视。20世纪以来,国内外安全疏散技术发展迅速,使得公共聚集场所人员疏散安全得到了有力保障。本毕业论文从国内外的公共场所安全疏散的发展历程与现状出发,通过对比分析,了解国外先进的疏散模型与技术,发现我国在安全疏散方面存在的缺陷。并按由简单到复杂的顺序,利用buildingEXODUS和CA模型对一些建筑结构进行疏散模拟,发现出口宽度,出口数量,出口位置,人员密度等对疏散时间的影响;又结合Origin软件,作出函数图像,探索建筑出口结构与安全疏散的关系。21423

Simulation and experiment study on occupant evacuation based on buildingEXODUS module
Abstract:With the development of society and the advancement of technology, all of our people have been clearly aware of safety concept and they try their best to keep their life and property safe. But there are always so many accidents happening in public gathering places home and abroadeveryday. Therefore, the problem which is safe evacuation of public gathering places has gradually drew our more and more attention. Since 20th century, safety in public gathering places has received effective guarding after the great leap in global evacuation technology. The article begins with the development and current situation of safe evacuation in public gathering places all around world. The advanced evacuation modules and technology are really impressive after comparison and analysis, and the disadvantages among Chinese evacuation study are obvious. Also, from simpleness to complexity, to find out how exit quantity, exit location, human density, etc influence evacuation time,several simulations for some buildings by buildingEXODUS &CA module have been made. Finally, to study the relation between building’s exit structure and safe evacuation, some functional images have been drew with Origin supporting.
