采用元胞自动机模型对两层楼的人员疏散进行了模拟,重点研究了楼梯的长度、楼道的宽度、楼梯的宽度、房间门的宽度对疏散时间的影响.结果表明疏散时间随着楼梯长度的增加影响不大,随着楼梯的宽度的增加疏散时间减少,在一定的条件下随着楼道宽度的增加疏散时间会有增加的趋势.该模拟结果对楼梯、楼道、楼梯长度的设计和行人疏散等方面具有一定的参考意义.
Using the cellular automaton model, the evacuation of two floors is simulated and the study focused on the relationship among the evacuation time and the length of the stairs, the width of the corridor, the width of the staircase, the width of the door. The results show that the increase of the length of staircase has little effect on the evacuation time. With the increase of the width of staircase the evacuation time is reduced, and under certain conditions if the width of the corridor is increased, the evacuation time will be increased. The results of simulation, to some extent, have reference value to the design of the staircase and corridor, as well as the length of staircase and pedestrians evacuation.
