垂直升船机初期火灾疏散方案仿真优化研究

为提高垂直升船机初期火灾疏散效率， 通过分析垂直升船机的结构及疏散通道，确定垂直疏散路径；根据承船厢停靠规则，比较计算楼梯疏散时间、电梯疏散时间，确定垂直疏散时间；运用仿真技术，模拟分析不同停靠高程下的疏散时间，以垂直疏散时间最短为目标，求解最优疏散方案。案例结果表明：停靠高程与下游疏散平台之间距离逐渐增大时，楼梯、电梯疏散时间先增大再减小，并且适当减小楼梯使用比例能够有效缩短疏散时间、提高疏散效率。

Simulation Optimization of Initial Fire Evacuation Schemes for Vertical Ship Lift

In order to improve the efficiency of fire evacuation in the initial stage of the vertical ship lift and reduce the evacuation time, the structure and evacuation channel of the vertical ship lift are analyzed to identity the vertical evacuation path. The vertical evacuation time is determined by comparing the evacuation time of stairs and elevator based on the docking rules of cargos. Aiming at the shortest vertical evacuation time the evacuation time of the different docking elevations is simulated to obtain the optimal evacuation plan. The results show that, when the distance between the docking elevation and the downstream evacuation platform increases gradually, the evacuation time of the stairs and elevators schemes increases first but decreases later, and the appropriate reduction of the proportion of stairs can effectively shorten the evacuation time and improve the evacuation efficiency.
