摘　　要：以上海某游乐园一场馆为例,利用FDS分析对于特殊小室空间场所火灾规模的确定方法,模拟不同排烟方式下的火灾发展情况,确定排烟方式,给出场景内的温度、能见度、CO分布。模拟结果表明:排烟方式、排烟口与补风口的设置、火灾控制综合影响游艺类场所内的火灾发展。结果可指导安全疏散策略的制定,为该类建筑的消防设计提供参考。Take a venue in an amusement building as example,the method of confirming the fire size for small space was analyzed by FDS,fire spread was simulated under different smoke exhaust methods and fire parameters were obtained including temperature,visibility and the concentration of CO.The results showed that fire spread could be influenced by smoke exhaust type,set of smoke exhaust vent and return air vent and fire control,which could guide the plan of safe evacuation and give reference for fire design of similar building.
