摘要
结合相关防火规范,介绍了地下建筑火灾烟气的特点及流动扩散规律,以某高校地下机房为例,对其烟气扩散状况进行了CFAST区域模拟分析,针对其防排烟系统提出了相应的改进措施,对同类地下建筑的防排烟设计有指导意义。
Unifying relevant fire-prevention norms, it describes features of the underground building fire smoke and the flow diffusion law. Taking the underground computer lab of a university for example, it carries on CFAST regional simulation analysis on smoke diffusion condi- tion. In light of its smoke-prevention and smoke-diffusion system, it puts forward corresponding improvements, which has guiding significance for similar smoke-prevention and smoke-diffusion design of underground buildings.
