摘要
为分析垂直升船机火灾疏散效率,从疏散人群的年龄结构、人流密度、人流速度等三方面,定量分析人群特性对疏散的影响;依据应急疏散路径,划分三阶段疏散时间,构建疏散时间模型;利用仿真技术,建立载有客船的垂直升船机模型,设置各项参数,求解火灾疏散时间。三峡升船机实例表明:垂直升船机本体火灾疏散时间远大于过机客船;承船厢左侧通道完成疏散时,3号疏散通道的流速大于2号;承船厢两侧通道完成疏散时,3、4号疏散通道的流速大于1、2号。
In order to analyze the fire evacuation efficiency of vertical ship lift, the influence of population characteristics on evacuation is analyzed quantitatively from three aspects, such as age structure, population density and flow velocity. According to the emergency evacuation path of vertical ship lift, the three-stage evacuation time is divided into three parts. In order to obtain fire evacuation time,the model of vertical ship lift with the passenger ship is established and parameters of evacuation time are set up by using the simulation technology. The actual case of the Three Gorges ship lift shows:1) the evacuation time of vertical ship lift is much larger than that of the passenger ship;2) when people complete evacuation through left side of carrying vessel, the flow velocity of No.3 evacuation passage is faster than that of No.2;3) when people complete evacuation through two side of carrying vessel, the flow velocity of No.3 and No.4 evacuation passage is faster than that of No.1 and No.2.
