高层建筑火灾最佳疏散路线的确定
|
摘要
高层建筑发生火灾后,在现场情况比较复杂的情况下,尽快地选择一条既安全、疏散时间又短的疏散路线,是室内人员快速、安全撤离火场的重要保障。在应用高层建筑火灾全风网网络模拟软件HRBFS模拟火灾时建筑物内烟流体积分数的基础上,结合当时人员的分布情况,提出了最佳疏散路线的算法。
Choosing an evacuation route that is safe and short in evacuation length as quickly as possible is an im-
portant safeguard for personnel evacuating building safely and quickly during high-rise building fire. On the base of
network simulator HRBFS (a high-rise building fire simulator), which can simulate the smoke concentration distri-
bution with time, and combine the personnel distribution in the building, the paper brings forward a method of the
best evacuation route during high-rise building fire.
