摘　　要：以半地下汽车库作为烟气控制研究对象,运用FDS软件模拟计算半地下汽车库发生火灾时产生的烟气在车库内的流动情况,并且通过分析发生火灾时温度和烟气层的能见度、高度等参数研究半地下车库的有效排烟-补风方式。结果表明:在一定的建筑结构、周边环境及地形条件下,可以采用顶部自然排烟口(采光通风井)和高侧窗补风的自然排烟补风方式代替整个防火分区机械排烟设计。Smoke control and air supply mode was studied for a semi-underground ear park of a residential district. Using FDS to calculate the flow of generated smoke by fire in the semi-un- derground car park , and by analyzing the parameters of smokelayer temperature and visibility, carbon monoxide concentra- tions in case of fire, the effective smoke exhaust and air supply mode in semi-underground car park waer investigated. Results show that under certain building structure, the surrounding en vironment and terrain conditions, the natural smoke exhaust and air supply mode can be used in a natural smoke exhaust （day lighting and ventilation shaft） and high side window venti- lation, instead of mechanical smoke exhaust design with the whole fire partition.
