摘要:
［目的］既有分区段发车能力研究未考虑到地铁车辆基地一体化发车全流程中的能力瓶颈及平行作业过程，应当聚焦列车从停车列检库运行至正线站台的全过程，系统分析发车能力瓶颈，提出地铁车辆基地早高峰一体化发车能力计算方法，为地铁车辆基地的发车能力评估与优化提供理论支撑。［方法］基于区段划分方法，分别研究列车进路方式、列车进路和调车进路相结合方式下的车辆段内咽喉区通过能力，以及不同加车径路下的段外接轨站加车能力。引入作业时间表和时距图分析，建立精细化能力计算模型。进一步分析分区段的能力瓶颈及平行作业过程，针对单线出段和双线出段两种方式，提出车辆基地一体化发车能力计算方法。将理论数值计算结果与广州地铁6号线萝岗车辆段实际运营数据进行对比，以验证方法的可靠性。［结果及结论］广州地铁6号线萝岗车辆段双线出段方式下，早高峰期理论最小发车间隔为223.6 s，对应最大发车能力为17列/h。实际运营中，早高峰期发车间隔为222.6 s，实际出段列车数量为17列，与理论值误差仅为0.45%，验证了数值计算的可靠性。
Abstracts:
［Objective］ The capacity bottlenecks and parallel operations throughout the full-process of integrated train dispatching from metro vehicle bases are not fully touched in existing section-based dispatching capacity studies. Therefore, it is necessary to focus on the complete process of trains operating from the stabling and inspection garages to the mainline platforms, systematically analyze dispatching capacity bottlenecks, and propose a calculation method for the integrated dispatching capacity of metro vehicle bases during morning peak hours, providing theoretical support for the evaluation and optimization of depot dispatching capabilities. ［Method］ Based on the section division method, the throat area passing capacity within vehicle depot under train routing and coordinated dispatch-routing modes, as well as the additional train insertion capacity at connection stations under different insertion routes, a detailed capacity calculation model is established by introducing operational timetables and time-distance diagrams. Further analysis is conducted on the capacity bottlenecks of different sections and the parallel operation processes. For both single-track and double-track dispatching scenarios, an integrated dispatching capacity calculation method for metro vehicle bases is proposed. Theoretical calculation results are compared with actual operational data from the Luogang Depot of Guangzhou Metro Line 6 to verify the reliability of the method. ［Result & Conclusion］ Under the double-track dispatching mode at the above-mentioned depot, the theoretical minimum dispatching interval during morning peaks is 223.6 seconds, corresponding to a maximum dispatching capacity of 17 trains per hour. In actual operation, the observed dispatching headway during morning peaks is 222.6 seconds, with 17 trains dispatched, resulting in a deviation of only 0.45% from the theoretical value, thus verifying the reliability of numerical calculation.
