用GIS与虚拟现实技术模拟火灾过程——应用和展望

Abstract

信息技术的发展已使得用计算机来模拟灾害过程及进行指挥救援成为可能。通过对国内外文献的分析,总结了GIS和虚拟现实技术在当前火灾模拟与控制方面的应用以及二者集成应用于火灾科学研究的可行性,并在此基础上提出了建筑火灾及人员疏散模拟系统的设计框架。该系统可针对现有和新建建筑,研究火灾发展及其可能对结构造成的影响,并进行人员疏散模拟与火灾危险性分析。 The development of information technology has led both of the computing-based disaster-simulating process and life-saving management have become possible. After reviewing and analyzing this field-related and relevant research articles, this paper is to summarise the applications of GIS and virtual reality technologies in the perspective of fire disaster’s simulation and control, as well as the possibility of their applicable integration on the fire disaster-related scientific research, and meanwhile, based on these previous research bases, to propose a newly designed plan for a system of a fire in a building and evacuation of people. This proposed new system implemented in both existing buildings and new constructions assists not only on the research of fire-disaster development and the possible influences of the corresponding structures but also the analyses of evacuating victims and the risk of a fire.
