摘要:
［目的］为支撑宁波市域形成“一主、一副、多中心”的市域空间格局的南翼重要辐射线，特对宁波市域铁路象山线(以下简称“象山线”)开行快慢车模式下的配线方案设计进行研究。［方法］依据客流预测结果，深入剖析全线断面客流及组团客流的特征，并计算长距离通勤客流在本线客流中的占比，以此为基础，研究判定开行大站快车的必要性。结合本线的行车间隔、行车对数以及慢车与快车在线路上的运行时分，科学计算越行站的设置数量及其具体位置。同时，兼顾换乘便捷性要求，以提升客流服务水平；并依据线网规划，综合考量折返功能、远期延伸需求及工程条件预留，全面规划全线配线方案。［结果及结论］遵循象山线的功能定位及规划标准，最小行车间隔设定为2.5min，结合牵引计算结果及停站时长，确定在塘溪站与大徐站设置越行站并配备越行线。大目湾站作为初期终点站，站后配置交叉渡线以满足折返作业，并预留延伸条件。横溪站作为规划宁波轨道交通12号线与象山线的接轨站及车辆段接轨站，站前与站后均设置交叉渡线，以满足接轨、折返及存车需求。南部新城站作为停车场接轨站，站后设停车场出入线及交叉渡线，确保折返与存车功能的实现。云龙火车站增设站前单渡线，以增强运营灵活性；贤庠站站前则配置故障车停车线及单渡线，以满足故障车辆的停放需求。
Abstracts:
［Objective］ To support the important radial line development of the southern wing in Ningbo′s spatial framework featuring ′one core, one auxiliary and multiple centers′, the track allocation scheme for the Ningbo City Railway Xiangshan Line under express/local train operation mode is examined. ［Method］ Based on passenger flow forecast results, the characteristics of cross-sectional passenger flow and cluster flow along the entire line are analyzed, calculating the proportion of long-distance commuting passenger volume within the total passenger flow. On this basis, the necessity of operating limited-stop express trains is determined. Considering operational intervals, train frequencies, and the runtime differences between express and local trains, the number and locations of overtaking stations are scientifically calculated. Interchange convenience is also considered to improve service levels for passengers. Additionally, the comprehensive track allocation plan for the entire line is developed by accounting for network planning, turn-back functionality, future extension needs, and engineering reserve conditions. ［Result & Conclusion］ In accordance with the functional positioning and planning standards of the Xiangshan Line, the minimum operational interval is set at 2.5 minutes. Traction calculation results and station dwell times determine that overtaking stations and lines should be established at Tangxi Station and Daxu Station. Damuwan Station, as the initial terminal station, will feature a crossover after the station to facilitate the turn-back operations and reserve conditions for future extension. Hengxi Station, planned as the junction station with Ningbo Rail Transit Line 12 and the depot access station, will include crossovers both before and after the station to accommodate connections, turn-back, and train storage needs. The Southern New City Station will serve as the depot access station, with outbound and inbound depot tracks and a crossover after the station to ensure turn-back and storage functionality. Yunlong Railway Station will add a single crossover before the station to enhance operational flexibility, while Xianxiang Station will feature a faulty vehicle parking track and single crossover before the station to meet the requirements for parking faulty trains.
