某大学学生宿舍楼火灾危险性研究

Study of the Fire Hazard of a College Dormitory

以某学生宿舍楼为对象,采用FDS和EVACNET计算了火灾烟气流动情况和人员疏散时间,根据计算结果研究了宿舍楼的火灾危险性。提出了起火层优先疏散方案,研究表明该方案能大大缩短危险楼层人员疏散时间。对比了楼梯防火门开启和关闭两种情况下宿舍楼的火灾危险性,定量分析了常闭式防火门在日常消防安全管理中的重要作用。

The smoke＇ s propagation and people＇ s evacuation in a student dormitory have been simulated using FDS and EVACNET. The fire hazard of the dormitory is studied according to the results. The concept of ＂priority in fire floor＂ is used in evacuation scheme, and the result shows that the evacuation time is decreased observably in fire floor. The fire hazard in case of stair has a fire door open and close is compared, and proves the necessity of fire doors close in student dormitory.
