摘　　要：在城市轨道交通封闭的运营环境中,一旦发生故障导致行车短时中断情况时,容易造成客流在站点的聚集,使一定范围出现拥挤现象.为了研究行车短时中断情况的拥挤影响范围,首先,分析短时中断情况下乘客的出行特征,然后以中断线路上的换乘站点作为研究对象,分析换乘站站台客流的组成,并计算站台的聚集客流量;其次,将SIR模型运用到拥挤范围研究中,通过站点间的客流流动情况对拥挤传播速率及消散速率进行量化,计算得到拥挤客流随着列车的运行对其上下游的影响范围;最后结合拥挤站点站台聚集客流随时间的变化情况,对拥挤影响范围进行量化,并以北京地铁5号线故障时的大屯路东站为例,分析了故障造成的影响范围,验证了模型的可行性.In the closed operating environment of urban rail transit, a short-term interruption by a failure could cause the passenger flow to gather at the station and spread within the system, thus causing congestion in a certain range, bringing inconvenience to the passengers and increasing the operation risk of rail transit. In order to study the influence range of congestion in the case of short-time interruptions, this paper first analyzes the travel characteristics of passengers under the short-term interruption, then analyzes the composition of the passenger flow at the transfer station platform, and finally calculates the aggregated passenger flow at the platform. Secondly, the SIR model is applied to the study of congestion scope. The congestion propagation rate and dissipation rate are quantified through the passenger flow between stations, and the influence range of the overcrowded passenger flow on the upstream and downstream of the train is calculated. Finally, the influence range of congestion is quantified in combination with the change of passenger flow on the crowded station platform over time, and the influence range caused by the failure of Beijing Metro Line 5. The feasibility of the model is verified by using a failure at the Datun Road East station.
