摘要
研究火灾的发生、发展规律,预测其危险性是有效预防和扑灭火灾的关键;随着计算机技术的迅猛发展,火灾数值模拟技术得到迅速的发展,成为火灾科学研究的重要工具;文中使用FDS构建建筑物模型,并追踪火灾及火灾烟气的产生和移动,结合家具、墙壁、地板和顶棚的材料特性来计算火灾的增长和蔓延;最终编写火灾数据分析平台FireSim,读取和分析FDS的输出数据,研究烟气层高度、温度、CO浓度和CO2浓度与建筑物中人员疏散安全时间的关系,并对火灾的危险状态给予评价,以便人们进行防火减灾工作,制订防灾救灾措施,确定火灾人员撤退范围、制订火灾人员逃生路线。
The Research of fire occurrence and the law of development, and the prediction of the risk are the key to prevent and extin- guish the fire effectively. With the rapid development of computer technology, fire simulation technology has been developed rapidly and has became an important tool in fire science research. This paper uses FDS to build the building model and track the production and movement of fire and smoke, combined with the material properties of furniture, walls, floors and ceiling to calculate the growth and spread of fire. Final- ly, we write the data analysis platform FireSim to read and analyze the output data of FDS, and give the fire danger rating. Meanwhile we re-search the relationship of evacuation time and the index, such as CO concentration, so as to help people prevent fire and reduce disaster.
