Taking a large indoor water amusement park as an exam?ple, the problems of overlarge area of fire compartment and over?long safety evacuation distance were analyzed, and using fire safe?ty engineering method,the countermeasures were proposed to strengthen the fire safety of the building. Through setting of the fire scenarios, taking into consideration of failure of automatic fire extinguishing system and smoke exhaust system, smoke spread and people evacuation were simulated by FDS and Pathfinder soft?ware, the practicality was assessed, the results could give refer?ences for fire design of similar projects.%以某大型室内水上乐园为例,对其消防设计中存在的防火分区面积超大和安全疏散距离超长的问题进行分析,利用火灾安全工程学的原理和方法对建筑消防设计提出加强措施.并通过设定火灾场景,考虑自动灭火系统和排烟系统失效的情况,利用FDS和Pathfinder软件进行烟气运动模拟和人员疏散安全性分析,以验证加强性措施的可行性,结果可为同类工程的消防设计提供参考.
