摘要
地铁车站站厅层的防排烟设计可参照《建规》进行设计,但站台层的防排烟除了面积指标外,需"应保证站厅层到站台的楼梯和扶梯口处具有不小于1.5m/s的向下气流",这一需求对系统的整体设计带来更高的要求。本文通过对火灾时排烟效果的模拟计算,分析地下车站站台层火灾的特点,提出了一些看法。
The smoke exhaust design of waiting room of metro station can refer to the provisions of ＂Code of design on building fire protection and prevention＂, but ＂Code for Design of Metro＂ prescribes that it must be ensured that ＂the downward flow is not less than 1.5 m/s in the places from the waiting room to the staircases and escalators of the platform＂. The demand for smoke exhaust of the platform brought about higher requirements to the overall design of the system. This paper focus on the fire smoke characteristics of underground station platform though the effects of fire smoke simulation and give some opinions.
