摘　　要：城市轨道交通系统在运营中可能发生设备故障、信号故障、供电故障等突发事件,运营安全性和系统服务能力的保障有待提升。本文旨在研究事故不确定性下的轨道交通线路韧性优化方法,根据事故站点和事故时间的不确定性,以供给侧和需求侧韧性最大为目标,考虑事故下大小交路列车行车间隔约束,基于运营事故大数据、乘客刷卡数据和列车运行时刻表构建折返线配置韧性优化模型。结合模型特征,设计基于样本均值近似、快速非支配排序、拥挤度计算的求解算法,对所提出的韧性优化模型进行求解。以北京地铁6号线为例验证模型的有效性,结果表明,该方法得到的最优折返线位置可以有效提升事故不确定性下的线路韧性。The urban rail transit system is vulnerable to emergencies such as equipment failures,signal malfunctions,power supply disruptions,making operational safety and service enhancement critical priorities.This paper investigated a resilience optimization method for rail transit lines under accident uncertainty,considering the uncertainty of both accident locations and times.With the goal of maximizing the resilience of both the supply and demand sides,considering the constraints on train headways for major and minor routes under accidents,a resilience optimization model for the return line configuration was proposed based on big data,including operational accident records,passenger card swiping data,and train operation schedules.Based on the characteristics of the model,a solution algorithm was designed incorporating sample mean approximation,fast non-dominated sorting,and congestion calculation techniques to address the model’s complexity effectively.A case study on Beijing Metro Line 6 demonstrated the practical applicability and efficiency of the method.The results show that the proposed approach can identify optimal turnback locations,significantly enhancing line resilience under accident uncertainty.
