an evacuation time model for passengers from metro platforms is proposed from field data by considering crowd density and physical characteristics of stations.
several common calculation methods of evacuation time have also been summed up.
总结了目前常用的疏散时间计算方法;
it is passed in an expert meeting guided by the fire bureau that the limited area of fire zone can be enlarged on condition that the evacuation time is guaranteed.
在消防部门指导下的专家论证会通过:在确保疏散时间前提下,可适当放宽中庭防火分区面积限制。
it is concluded that the evacuation time is relatively long for the low pressure location.
研究结果表明,在低压力区域,抽气时间相对较长。
the results show that the mixture evacuation style by using stairways and elevators will decrease the evacuation time effectively.
采用楼梯和电梯相结合的混合疏散方式可以有效地提高疏散效率。
evacuation time mainly relates to the aisle width of the door and the number of pedestrians.
疏散时间主要和走道门的宽度、行人的数量有关;
also the relationship between the evacuation time lengths and the floor numbers, as well as the people densities, was got from the analyses of office floors.
并针对办公区楼层进行分析,得出办公区楼层的疏散时间与人员密度、建筑层数成正比关系。
the results obtained evacuation time and the number of stairs, corridor width, stair width, and pedestrians in the corridor, stairs bias strength of relationship.
结果得出了疏散时间与楼梯的数量、楼道宽度、楼梯宽度以及行人在楼道、楼梯偏向强度的关系。
the crowd evacuation time in a fire includes the preevacuation delay time and the travel time.
火灾中人员的疏散时间主要包括疏散前的延迟时间和在通道上的疏散时间。
the calculation method on evacuation time for drying of long-distance pipeline at the state of water free is analyzed. the calculation equations are given and identified by field test.
earthquake has a close connection with the evacuation status and time of rescuing, the writer of this paper sets forth the necessity of constructing an evacuation time model on campus.
