豪华邮轮不同楼梯布置的乘员疏散效率分析

Evacuation Efficiency Analysis of Occupants in Luxury Cruise Involving Different Layout Conditions of Stairs

针对豪华邮轮乘员疏散效率问题,采用数值模拟的方法对不同楼梯布置下的疏散过程进行模拟,并对影响人员疏散的楼梯布置条件进行对比,结果表明,疏散楼梯的宽度与疏散效率并不是正相关的关系,适当减小楼梯宽度可以有效提高人员疏散效率;只考虑增加楼梯数量,不会使疏散效率有明显改进;同时考虑适当减小楼梯宽度、增加楼梯数量和楼梯空间布局可以大幅减少总疏散时间,疏散总时长最多能缩短21.51%。

To explore the influence of the stair arrangement of luxury cruise upon the evacuation efficiency of occupants, numerical simulation method was used to simulate the evacuation process under different layout conditions. The comparison of the stair layout conditions affecting the evacuation efficiency of occupants was carried out. Results showed that the width of stairs was not positively related to the evacuation efficiency. By changing the width of stairs or increasing the number of stairs solely will not significantly improve the evacuation efficiency. After optimization, the total evacuation time could be reduced greatly-and shortened by up to 21.51%.
