摘要:
［目的］通过总结上海城市轨道交通既有线运能提升改造项目的实施经验，为其提出有效的运能提升方法及具体案例。［方法］深入分析上海轨道交通既有线运能不足的主要原因及其影响因素；基于这些分析，提出运能提升的技术路线及5大核心策略；详细介绍了上海轨道交通9号线实现1min50s最小行车间隔、3号线与4号线增能改造、5号线从4节编组扩编至6节编组、6号线增能改造及增设复线等成功案例。［结果及结论］影响线路运能的主要因素包括车辆基地规模、区间通过能力、出入场能力，以及供电能力等。针对这些因素，确定了运能提升的技术路线，即从客流预测及客流特征分析入手，进行设施设备能力评估，设计行车交路方案，最终形成科学的改造方案。同时，提出了5大策略：运营管理优化、既有系统能力挖潜及改造、信号系统升级或土建局部改造、系统规模性改造及线网整体优化。
Abstracts:
［Objective］ Aiming to propose effective methods and specific cases for capacity enhancement, the implementation experiences of capacity improvement renovation projects on existing Shanghai urban rail transit lines are systematically summarized. ［Method］ An in-depth analysis of the main reasons and influencing factors behind the insufficient capacity of existing Shanghai urban rail transit lines is conducted. Based on these analyses, the technical approach and five core strategies for capacity enhancement is outlined. Successful cases are introduced, including the achievement of 1-minute 50-second minimum departure interval on Line 9, the capacity enhancement renovation of Line 3 and Line 4, the expansion reconstruction of Line 5 from 4-car to 6-car trains, and the capacity enhancement renovation and double-track addition on Line 6. ［Result & Conclusion］ The key factors influencing line capacity include vehicle depot size, interval throughput, depot entry/exit capacity, and power supply capacity. Addressing these factors, a technical approach for capacity enhancement is established, which starts with passenger flow prediction and characteristics analysis, followed by facility and equipment capacity assessment, and train routing scheme design, ultimately leading to the development of scientifically sound renovation plans. Additionally, five major strategies are proposed: optimization of operational management, digging into and upgrading existing system capacity, signaling system upgrades or localized modifications of civil works, large-scale system overhauls, and line network overall optimization.
