南京枢纽新建南京北动车所的必要性及整体布局方案研究

针对国内在新建高速铁路枢纽内,动车组配属及承担动车段(所)动车组检修工作量、检修设施规模的测算结果中表现出的不统一、不协调及不匹配等问题,本文以新建南京枢纽南京北动车所工程项目为依托,研究确定枢纽内动车组配属规模设计、承担动车段(所)动车组检修工作量及检修设施规模测算理论,提出了以全周转时间及日车公里法为指标的2种枢纽...

Study on Necessity and Overall Layout of Nanjing NorthMultiple Units Depot at Nanjing Hub

Aiming at the disunity,disharmony,and mismatch in the calculation of EMU assignment and maintenance workload and maintenance facilities scale in newly-built high-speed railway hubs in China,this paper,based on the newly-built Nanjing North Multiple Units Depot at Nanjing Hub,studies and determines the design of multiple units assignment scale at hubs,the calculation theory of multiple units maintenance workload and maintenance facilities scales,and puts forward two calculation methods of multiple units assignment scale at hubs with total turnover time and daily car running legnth method as indicators.The results show that when the average daily car running legnth of multiple units in the hub is 2000 km calculated by common experience,the number of the used multiple units and spare multiple units calculated without considering the number of overhauled multiple units is about 41%higher than that calculated by the total turnaover time calculation method,the number of assigned multiple units are about 20%higher,and the number of storage lines and inspection lines of multiple units is about 35%higher.The number of assigned multiple units in the hub is calculated.
