摘要
为了解楼梯布局对客船人员疏散效率的影响,基于烟台—大连的滚装客船的人员组成和船舶熟悉程度的调查结果,利用FDS+EVAC建立客船疏散仿真模型,通过设置不同的楼梯布局方案,计算疏散时间和疏散效率.结果显示:在客船的主楼梯上增加间隔扶手可以有效分散人流,提高主楼梯处的人员疏散效率,缓解拥堵现象;但是,在主楼梯处增加间隔扶手过多,反而导致总体疏散时间变长.考虑到建造成本和人员行走的便捷性,建议在主楼梯处增加1个间隔扶手.本文建立的客船疏散模型可供识别现有客船几何布置的拥堵点,优化船舶楼梯设计,提高客船人员疏散效率.
To understand the influence of staircase layout on the evacuation efficiency of passenger ships,a passenger ship evacuation simulation model was established by using FDS+EVAC based on the survey results of the population composition and the familiarity of the ship of the Ro-Ro passenger from Yantai to Dalian.The evacuation time and evacuation efficiency were calculated by setting different staircase layout scenarios.The results show that increasing handrails at the main staircase of passenger ships can effectively disperse the flow of evacuation,enhance the efficiency of evacuation at the main stairs,and ease congestion phenomenon.However,too many handrails in the main staircase will increase the overall evacuation time.Considering the construction cost and the personal walking convenience,it is suggested to increase one handrail to the main staircase.The passenger ship evacuation model established in this paper can be used to identify the congestion points of the existing passenger ship geometry layout,optimize the design of ship staircase,and improve the efficiency of passenger evacuation.
