地铁高架长大区间非正常情况下行车组织探究

地铁高架长大区间既具有高架线路的特点又具有长大区间的特点,其非正常情况下的行车组织具有一定的特殊性。通过分析恶劣天气、区间列车故障、区间信号故障对高架长大区间列车运行的影响,对这3种非正常情况下的行车组织方法进行探究与阐述。在恶劣天气情况下,应多渠道及时获取气象信息,根据恶劣天气的不同级别制定相应的限速、停运等相关措施,并预先建立相关应急预案。同一高架长大区间内存在两列列车运行的可能性较大,依此为前提进行分析,若发生需救援的列车故障时,应根据列车具体停靠位置选取不同的救援方案,再按步骤高效组织救援;若发生信号故障时,不能臆测故障内容,应以确保安全为首要任务,按步骤高效组织列车进站后,再进行相应行车组织调整。此行车组织方法对地铁高架长大区间非正常情况下的行车组织具有一定的指导性。

Train Operation Organization for Long Elevated Sections under Abnormal Conditions

The long elevated section of a metro has characteristics of both an elevated line and a long section,and the train operation organization under abnormal conditions has some particularities.By analyzing the influence of bad weather,train fault,and signal fault on train operation in long elevated sections,the train operation organization is explored and expounded under these three abnormal conditions.Under bad weather conditions,weather information should be timely obtained through various channels;relevant measures,such as speed limit and shut down,should be established according to the different levels of bad weather;and relevant contingency plans should be formulated in advance.In case of a train fault,the possibility of two trains running in a long elevated section is more likely,and thus,the rescue plan should be selected according to the train location,and then,the rescue should be organized efficiently.In case of a signal fault,to prioritize safety without guesswork,steps should be followed to organize trains into stations efficiently,and then to adjust the train operation organization.The methods described in this paper provide guidelines for the train operation organization under abnormal conditions in long elevated sections.
