摘要:
［目的］城市轨道交通车辆基地的上盖物业开发已成为上海、北京等诸多城市的车辆基地设计基本要求，为了有效解决上盖物业开发对盖下库房的影响，需对运用检修库房的净空高度进行研究。［方法］以车辆基地的运用库和联合车库作为研究对象，分析上盖开发车辆基地库房净空高度的主要影响因素，梳理运用检修库房净空高度设计流程；提出架空接触网制式和接触轨制式下的库房净空计算方法。［结果及结论］采用接触网制式时，需考虑接触网导线高度及安全距离、起重机走行轨轨顶标高及起重机高度、架空管线层高度、结构主梁高度等因素，停车列检库首层盖板的最小高度为7.5m；检修库(除停车列检库、临修库外)首层盖板高度统一为8.5m；临修库首层盖板的最小高度为13.5m。采用接触轨制式时，影响因素除接触网导线高度外，其余均与接触网制式一致，停车列检库、周月检库房首层盖板高度分别为7.5m和8.5m。
Abstracts:
［Objective］ The development of overhead property in urban rail transit vehicle bases becomes a basic requirement for vehicle base design in many cities such as Shanghai and Beijing. To effectively address the impact of overhead property development on the covered garages, it is necessary to study the clearance height of operation inspection garage. ［Method］ Taking the operation garage and the joint garage of vehicle base as research objects, the main factors affecting the clearance height of vehicle base garage with overhead property are analyzed, and the design process of operation inspection garage clearance height is sorted. Calculation methods for operation inspection garage clearance height under overhead catenary system and third contact rail system are proposed respectively. ［Result & Conclusion］ When using overhead catenary system, factors such as the height and safety distance of catenary wires, the top elevation of crane running track, the crane height, the overhead pipeline layer height, and structural main beam height need to be considered. The minimum height of the first-floor slab of parking inspection garage is 7.5 m; for inspection garages (excluding parking inspection and temporary repair garages), the first-floor slab height is uniformly set at 8.5 m; the minimum height of the first-floor slab of temporary repair garage is 13.5 m. When using contact rail system, apart from the height of catenary wires, the other influencing factors are consistent with the overhead catenary system. The first-floor slab heights of parking inspection and weekly/monthly inspection garages are 7.5 m and 8.5 m respectively.
