摘　　要：结合侗族木结构建筑火灾的危害及实地火灾调研,以现场测绘木结构建筑原型为研究对象,应用FDS软件进行木结构建筑室内火灾数值模拟研究。设置东宅大厅发生火灾,在不同位置距离楼面高1.5 m设置测量点,通过对火灾模拟中的燃烧特征、温度、烟气及含氧量等相关数据的采集与分析论证,得出多方位的侗族木结构建筑火灾危险性特征,指导侗族木结构建筑的防火设计及防火策略的实施。Combined with the damage of wood structure building fire of the Dong nationality and the field fire investigation,the field mapping of wood structure building prototype was used as the research object,and FDS was used to simulate the indoor fireo fwood structure building.The fire was set at east residence,and the measuring points at different locations 1.5 m above the floor were set.Through the data collection and analysis of combustion characteristics,temperature,flue gas and oxygen content in fire simulation,the fire risk characteristics of wood structure of Dong were obtained to guide the fire prevention design and implementation of fire prevention strategies.
