摘要
为能够在游船发生火灾时选择合理的疏散路径,避免和减少人员伤亡,引入当量长度,建立火灾时游船应急疏散模型,选用最短路径算法得到火灾区域至各逃生出口的多条最优疏散路径,并利用MATLAB编程实现.选取"海洋绿洲"号游船进行实证研究,在客舱着火点位置确定的情况下分别考虑游船通道阻塞和火灾扩散对最优疏散路径的影响.研究结果表明,所建立的疏散模型是可靠的。
In order to select a reasonable evacuation route to avoid or reduce injuries and deaths when the fire breaks out on cruise ship,the equivalent length is introduced to establish the cruise ship emergency evacuation model in case of fire.Dijkstra algorithm is adopted to get multiple shortest evacuation routes between the disaster area and the emergency exits,and the solutions are obtained by MATLAB.Cruise ship ＂Ocean Oasis＂ is selected to do the empirical research.In the case that fire in passenger cabin is known,the influences of path occupation and the expanding of fire on the optimal evacuation routes are discussed.The result shows that the evacuation model is of reliability.
