乘员折返行为对船舶疏散效率影响的计算分析

Calculation and Analysis of the Influence of Human Reentry Behavior on Ship Evacuation Efficiency

考虑船舶人员疏散的特点,对不同的人员折返比例对船舶疏散过程的影响运用Pathfinder软件进行仿真分析,疏散实验结果表明,随着人员折返比例的增大,疏散时间迅速增加,人员在出口附近的走廊处出现拥堵现象;在人员折返比例为40%时,折返行为对疏散效率的影响最大,对船舶布置进行优化后,疏散效果得到改善,疏散时间明显减少,拥堵程度得到缓解。

According to the characteristics of evacuation on ship,considering the impact of different reentry rates on ship evacuation process,the simulation experiments were carried out by using software Pathfinder.The results showed that with the increase of the reentry proportion,the evacuation time increased rapidly,and occurred congestion at the corridor near the exit.when the proportion was 40%,there had the greatest impact on efficiency and congestion was most serious.After optimizing the ship’s layout,the evacuation effect was improved,evacuation time was obviously reduced,and the congestion was alleviated.
