大型室内游乐场人员疏散运动时间的模拟

Simulation of Personnel Evacuation Movement Time in a Large Indoor Amusement Park

针对大型室内游乐场人员疏散运动时间的问题,分析了游乐场人员构成、人员步速和肩宽及其分布与人员疏散运动时间的关系,采用Pathfinder模拟了该运动时间与其影响因素间的关系.模拟结果表明:对于特定的大型室内游乐场,在外界环境和人员密度不变的条件下,人员疏散运动时间随人员步速的增大而减少,随人员肩宽的增大而增大,随儿童比例的增大而增大;人员步速和肩宽均服从常值分布时的疏散运动时间最短,服从均匀分布时的疏散运动时间最长,服从正态分布时的疏散运动时间介于二者之间.

For the problem of personnel evacuation movement time in a large indoor amusement park, the relationships between the personnel evacuation movement time and these factors including composition of people, walking velocity, shoulder width and distribu tion were analyzed. Pathfinder was used to simulate their relationships between the movement time and its influence factors. The results showed that for a particular large indoor amusement park, under the same conditions in the external environment and personnel density, evacuation movement time decreased with walking velocity increasing while increased with shoulder width increasing as well as with the proportion of children increasing. The resuhs also showed that when walking velocity and shoulder width were constant value or fit uni form distribution or standard normal distribution, the corresponding evacuation movement time could be determined as minimum, max im and medium.
