摘要
地下交通枢纽站火灾时烟气控制策略是人员疏散安全的重要因素。地下交通枢纽站科学合理设置机械排烟和送风,在火灾发生时,可以有效降低毒气造成的人体伤害,控制伤亡损失。选取广州珠江新城地下交通枢纽站作为分析案例,分析如何合理布置机械排烟口以及机械送风补风口,利用CFD技术分析地下交通枢纽站的排烟补风策略,比较三种烟控模式,探讨利于人员安全疏散的最佳烟气控制策略。
The fire hazard of underground transportation hub station has a big difference with that of over-ground floor,in there the fire smoke control strategy of underground public places is an important factor for evacuation safety.When underground public places have scientific and rational set of mechanical exhaust and supply air,if the fire breaks out,bodily injury caused by the smoke can be effectively reduced and the casualty loss can be controlled.The underground transport hub stations in Guangzhou Zhujiang New City was selected as a case to study how to arrange a rational smoke vent and air supply outlet,CFD was applied to analyze the smoke exhaust and air make-up policy of underground public places,and three smoke control modes were compared.Finally,the best smoke control strategies for human safe evacuation was explored.
