国家大剧院高大空间排烟系统的分析设计

Analysis and design of the large space smoke extraction system in the National Centre for the Performing Arts

利用自然排烟理论,根据理论计算参数,综合考虑建筑造型、使用安全等因素,对国家大剧院高大空间排烟系统进行分析与计算,得出采用自然排烟方法的各项技术参数。确定国家大剧院采用主壳体自然排烟与自然补风、机械补风、环廊机械排烟相结合的防排烟方案,确保了工程的使用安全。

By using the natural smoke extraction theory, based on the theoretical calculation parameter, and with a view to the architectural style, application safety and other factors, analyses and calculates the large space smoke extraction system of the theater, working out the technical parameters for natural smoke extraction. And determines adopting natural smoke extraction in the space of the main shell-body and mechanical smoke extraction in the annular corridor, with natural and mechanical smoke make-up, ensuring fire safety of the project.
