摘要
[目的]跨坐式单轨交通制式独特,在高架线路上进行疏散救援时不同于常规的城市轨道交通疏散救援形式,因此有必要对该制式下区间乘客疏散救援方式与疏散效率等进行深入研究。[方法]建立跨坐式单轨交通区间乘客疏散救援仿真模型,研究典型的三种不同区间乘客疏散救援方式的影响因素,探究疏散效率较高的救援措施;针对横向及垂向疏散救援场景,提出达到最佳疏散效率的救援设施设置位置与数量的确定方法;提出了更加科学合理的跨坐式单轨交通区间乘客疏散救援建议。[结果及结论]疏散影响因素方面,疏散救援设备放置位置与数量影响横向救援时间;消防云梯倾斜角度影响垂向疏散救援时间;工作人员的引导作用对跨坐式单轨交通区间乘客疏散救援有积极作用。在疏散效率方面,横向、纵向及垂向疏散救援方式中应当优先考虑横向救援方式;横向及垂向疏散救援设备放置位置应尽量使每块横向救援渡板上的疏散人数相同;采用垂向疏散救援时,疏散效率随着消防云梯倾斜角度的增加先减少后增加。
[Objective]Due to the unique characteristics of straddle monorail transit system,evacuation and rescue forms on its elevated lines differ from conventional urban rail transit.Therefore,it is necessary to conduct an in-depth study of interval passenger evacuation and rescue methods and evacuation efficiency for this system.[Method]A simulation model for passenger evacuation and rescue in straddle monorail transit intervals is established.The influencing factors of three typical interval passenger evacuation and rescue methods are studied and the rescue measures with higher evacuation efficiency are explored.For both horizontal and vertical evacuation and rescue scenarios,methods to determine the placement and quantity of rescue facilities for optimal evacuation efficiency are proposed.More scientific and reasonable suggestions for passenger evacuation and rescue in straddle monorail transit intervals are provided.[Result&Conclusion]Research results indicate that:in terms of evacuation influencing factors,the placement and quantity of evacuation and rescue equipment affect horizontal rescue time;the inclination angle of fire ladder affects vertical evacuation and rescue time;the guidance from staff positively impacts passenger evacuation and rescue in straddle monorail transit intervals.In terms of evacuation efficiency,horizontal rescue should be prioritized over longitudinal and vertical evacuation and rescue methods.The placement of horizontal and vertical evacuation and rescue equipment should ensure equal distribution of evacuees on each horizontal rescue board.For vertical evacuation and rescue,evacuation efficiency initially decreases and then increases with fire ladder inclination angle increasing.
