某超大型全地下高铁火车站防排烟系统设计

Design of Smoke Extraction System in Large-Scale Underground High-speed Rail Station

国内某超大型地下高铁火车站在工程设计中,充分利用消防性能化的设计成果,突破常规,在合理划分防火防烟分区面积、根据火灾场景计算出各区实际排烟量的基础上,合理进行排烟风机的选型;在综合考虑了车站的站址环境、建筑布局、外部接口、机房布置、风亭位置等特点的基础上,采用分区横向排烟的设计方案,避免了因建筑形式复杂、排烟距离过长等因素带来的不利影响,解决了此类复杂超规地下车站的防排烟问题。

This thesis describes the design of reasonable exhaust fan selection in large-scale underground high-speed rail station which based on full use of performance-based fire study reports, breaking the routine, reasonable dividing fire prevention smoke areas and actual calculating the amount of smoke in the district according to the fire scene, and introduces the project of horizontal partitioning exhaust design of the station to avoid adverse effects of complex architectural forms and long exhaust distance and to solve smoke control of such complex ultra conventional underground station which in consider of the characteristics of station site environment, architectural layout, external interfaces, room layout and wind pavilion location.
