为探究海拔高度对机场航空器旅客应急疏散的影响，构建机场航空器事故应急疏散仿真模型，通过引入恐慌因子、年龄因子、性别因子以及海拔修正系数，定量表征不同海拔环境下旅客行走速度，分析不同海拔高度、有无疏散引导、舱内过道间距及双航空器碰撞等工况下旅客疏散效果。结果表明：相对于平原，高高原环境下应急疏散时间影响主要体现在舱内疏散中后期和地面疏散阶段；海拔高度4 280 m时，与平原地区相比，舱内疏散时间增加19.6 s，总体疏散时间增加44.1 s；设置舱内机组人员引导，舱内疏散时间减少18.1 s，疏散效率提升16.5%；增加过道间距宽度至60 cm时，舱内疏散时间减少了20.8 s，疏散效率提升19%；相对于单航空器疏散，双航空器疏散时间显著增加，需要优化疏散策略。本文研究结果可为高高原机场航空器突发事件应急疏散方案优化提供理论支持。

In order to explore the impact of altitude on the emergency evacuation of aircraft passengers at airports, a simulation model for emergency evacuation of aircraft accidents at airports was built. By introducing panic factor, age factor, gender factor and altitude correction factor, passenger walking speed at different altitudes was quantitatively characterized, and passenger evacuation effects were analyzed under conditions such as different altitudes, with or without evacuation guidance, and cabin aisle spacing, dual aircraft evacuation. The results show that the impact of emergency evacuation time in a high plateau environment is mainly reflected in the middle and late stages of cabin evacuation and ground evacuation. When the altitude is 4 280 m, the cabin evacuation time is increased by 19.6 s and the overall evacuation time is increased by 44.1 s compared with the plain area. By setting cabin crew guidance, cabin evacuation time is reduced by 18.1 s and evacuation efficiency is increased by 16.5%. When the width of aisle spacing is increased to 60 cm, the evacuation time in the cabin is reduced by 20.8 s, and the evacuation efficiency is increased by 19%. Compared with single-aircraft evacuation, the evacuation time of dual-aircraft evacuation is significantly increased, so it is necessary to optimize the evacuation strategy. The research results can provide theoretical support for the optimization of aircraft emergency evacuation schemes at high plateau airport.
