摘要:
［目的］为提升车辆基地工程综合效益，节约工程投资，增强工艺设计技术储备及适应性，对市域（郊）铁路车辆基地运用库线设计方案进行研究。［方法］依托宁仪扬市域（郊）铁路工程，基于市域（郊）铁路车辆特点及行车组织方案，通过车辆运用检修标准、车辆运用检修工作量得到车辆基地的总设计规模，结合选址用地规模条件得到龙潭车辆基地和扬州西停车场运用检修设施的设计规模。从建筑基底面积、新增用地面积、铺轨长度及远期发展适应性等4个方面对比分析了龙潭车辆基地运用库线设施近、远期分期实施预留的设计方案，并提出了预留上盖开发及全自动运行条件的龙潭车辆基地总图布置方案。［结果及结论］龙潭车辆基地运用库线最终选定的方案为：采用4辆或6辆编组复合库线布局，实施1线2列位混合编组停车列检方案。库线前段按6辆编组标准建设，后段兼容4辆编组作业需求；末端预留向6辆编组标准长度扩展的接续条件，形成可扩展复合功能布局。运用库基底面积为30 304.8 m2，无新增用地面积，铺轨长度为4 095 m，远期发展适应性好。该分阶段实施方案可有效节约用地规模与建筑面积，提升车辆基地的近、远期经济效益。
Abstracts:
［Objective］ To enhance the overall efficiency of vehicle base engineering, reduce investment costs, and strengthen the technical reserves and adaptability of process design, research is carried out on the design schemes for operation workshop tracks in city (suburban) railway vehicle bases. ［Method］ Based on the Ningyiyang (Nanjing-Yizheng-Yangzhou) City (Suburban) Railway project and considering the characteristics of city (suburban) railway vehicles and operational organization plans, the total design scale of the vehicle base is determined through standards and workload related to vehicle maintenance and operation. The design scale for Longtan Vehicle Base and Yangzhou West Stabling Yard are derived in accordance with site land scale availability. A comparative analysis is conducted from four aspects—building footprint area, additional land area, track length, and long-term development adaptability—regarding phased implementation and reservation of Longtan Vehicle Base operation workshop tracks in near and long-term. Additionally, a general layout scheme for the Longtan Vehicle Base is proposed, incorporating reserved conditions for the over-station development and fully automated operations. ［Result & Conclusion］ The final selected design scheme for Longtan Vehicle Base operation workshop track adopts a composite layout with 4-car and 6-car train formations and implements a mixed formation parking and inspection plan for 2 trains on a single track. The front section of the workshop track is constructed based on the 6-car formation standard, while the rear section is compatible with 4-car operations. The end section reserves the conditions for further extension to 6-car formation standards, forming a scalable, composite-functional layout. The depot track facility covers a base area of 30 304.8 m2, requires no additional land, includes a total track length of 4 095 m, and provides strong adaptability for long-term development. This phased implementation scheme effectively conserves land use scale and building area while enhancing the near-and long-term economic efficiency of vehicle base.
