体育馆建筑内青年学生疏散预动作时间调查和分析

Investigation and analysis on pre-evacuation time of young students in the gymnasium

通过组织火灾应急疏散逃生演习、现场问卷调查等方式,统计了体育馆内人员的疏散预动作时间,进而建立多分变量逻辑斯蒂回归模型对该统计数据进行了研究。发现:男生选择疏散预动作时间为<30 s的可能性是女生的0.886倍,选择疏散预动作时间为30-60 s的可能性是女生的2.818倍。预测人员疏散预动作时间为<30 s、30-60 s、>60 s的概率,男生分别为15.45%,75.61%、8.94%,而女生分别为24.14%,39.72%、36.14%;研究结果表明:人员性别的不同对疏散预动作时间有一定的影响,在体育馆类建筑中,青少年人员疏散预动作时间基本上小于60 s。

Personnel pre-movement time in the gymnasium was studied by fire emergency evacuation drill and questionnaire survey.The Multinominal Logistic Regression Model was applied on analyzing survey data.The result showed that evacuation pre-movement time（30 s） spended by male is 0.603 times as long as one spended by female and evacuation pre-movement time（30 s-60 s） spended by male is 2.818 times longer than one spended by female.In public buildings represented by the stadium,the probability of male＇s evacuation pre-movement time（30 s,30 s-60 s,60 s） respectively is 15.45 %,75.61 %,8.94 % and the probability of female＇s evacuation pre-movement time（30 s,30 s-60 s,60 s） respectively is 24.14 %,39.72 %,36.14%.It showed that different gender has a certain effect on pre-evacuation time.In public buildings represented by the gymnasium,young students pre-movement time is less than 60 s.
