摘　　要：在存量城市空间紧约束的背景下,地铁车站站房建设逐渐深层化,站内自动扶梯呈现穿越层数多、提升高度大的趋势.地铁换乘枢纽站客流大,一旦发生紧急情况,极易造成人群拥堵,甚至踩踏等伤亡事故,其中,超长自动扶梯成为重点关注部位.根据超深地铁换乘枢纽地下空间面积大、层数多及内部结构复杂等特点,利用Revit组合MassMotion的建模仿真方法,以中国成都市4线地铁换乘枢纽骡马市站为例,模拟枢纽内超长自动扶梯故障对乘客出行造成的影响.通过设置超长自动扶梯故障场景,从微观角度模拟分析拥堵原因,制定限制方向和客流引导等疏散方案,减少乘客出行决策判断时间,优先保证更多乘客正常完成出行,缓解超长自动扶梯故障造成的客流拥堵.通过定量评估退出模拟用时与起讫点社会模拟成本等指标,发现虽然部分方向乘客的走行和候车成本增加,但整体出行用时降低.该方法可为地铁运营部门制定疏解预案提供参考.In cities with limited existing space,the construction of new metro stations increasingly focuses on efficient and intensive land use,with station designs trending towards deeper and more complex structures.Station escalators are now designed to span multiple levels and greater heights.High passenger flow in metro transfer hubs increases the risk of crowd congestion and stampede accidents during emergencies,making extra-long escalators a focal point of concern.Using Chengdu's Luomashi Station,a metro hub where four metro lines intersect,as a case study,we propose an integrated modeling method using Revit and MassMotion to account for the extensive underground space,multiple levels,and complex internal structure of ultra-deep transfer hubs.We simulate the impact of long escalator malfunctions on passengers within these hubs.By setting up scenarios of escalator failures and analyzing congestion causes from a micro perspective,we propose evacuation strategies such as directional restrictions and passenger flow guidance to reduce decision-making time,prioritize safe travel for more passengers,and alleviate congestion caused by escalator malfunctions.Quantitative evaluations of exit times and origin destination(OD)social simulation costs reveal that while the walking and waiting costs may increase for passengers in certain directions,overall travel time decreases.This research provides valuable references for metro operators in formulating contingency evacuation plans.
