摘要:
目的：为了使地铁车辆段工程设计方案更好地适应目前广泛采用的均衡修作业模式，需分析车辆均衡修设计对地铁车辆段设计的影响。方法：针对均衡修模式下的地铁车辆段，梳理了均衡修模式的修程、作业流程及作业时间，提出了工程设计时的均衡修修程及作业时间建议。提出设计规模和检修车数量计算方法，对相关线路及设施的配置方案开展研究。通过对系统修模式和均衡修模式的车辆检修周期、作业内容、作业时间和作业流程分析，比较两种模式的设计规模和检修车数量计算结果，以及所需的线路及设施，总结均衡修模式带来的影响。结果及结论：车辆均衡修模式与《地铁设计规范》规定的车辆检修修程存在较大差异，影响了车辆段的设计规模、配属车数量及线路设施需求等。采用均衡修模式后，轻型检修台位数量可降低18%，检修车数量可降低57%。可见，地铁车辆段工程宜按照均衡修模式进行设计。均衡修模式下应取消定修线，不承担车辆大架修作业的车辆段可取消静调线，停车场不应因为均衡修而增加试车线。现行《地铁设计规范》不适应均衡修模式，建议对相关条文进行修订。
Abstracts:
Objective: To better adapt engineering design proposals of metro vehicle depots to the widely adopted BMO (balanced maintenance operation mode), the impact of vehicle BMO on the design of metro vehicle depots is analyzed. Method: For metro vehicle under BMO, the maintenance schedule, workflow, and duration associated with this mode are examined, and recommendations for BMO duration and operation time during engineering design are proposed. Calculation methods for determining the scale of design and the number of maintenance vehicles are presented, and research is conducted on the configuration schemes of related lines and facilities. By analyzing the maintenance cycles, tasks, durations and workflows of the system maintenance mode and BMO, the design scale and the calculated number of maintenance vehicles between the two modes, as well as the required lines and facilities are compared. The impact brought about by BMO is summarized. Result & Conclusion: There is a significant difference between the vehicle maintenance duration regulated by the vehicle BMO and the Code for Design of Metro, affecting the design scale, allocation of vehicles, and requirements for line facilities in vehicle depots. After adopting BMO, the required amount of light maintenance platforms can be reduced by 18%, and the number of maintenance vehicles can be reduced by 57%. It is evident that metro vehicle depot engineering should be designed according to BMO. Under BMO, scheduled maintenance lines should be removed, static adjustment lines can be canceled for depots not undertaking vehicle overhaul tasks, and test tracks should not be added to parking lots due to BMO. The current Code for Design of Metro is not suitable for BMO, and it is recommended to revise the relevant provisions accordingly.
