成都动车段总平面布置设计

Design for General Plan of Chengdu Electric Multiple Unit Depot

动车段是满足高速铁路动车组安全、正点运行的重要设施,全路动车段布点按照服务局域路网进行设置。成都动车段是在原路网规划的4个动车检修基地的基础上增设的3个动车检修设施之一,其建设完善了路网动车组检修布局,填补了西南地区动车组检修空白。阐述了成都动车段段址选择、功能定位、规模设计,通过对线路、房屋、道路以及检修设施等布置的研究,采用总平面按纵向错列式布置、检修库房集散统一布置、检查库前采用双排股道布置等方式,提高动车组检修效率,同时也降低了工程投资。

EMU(electric multiple unit) depot is an important facility,which must meet the requirements of safe and punctual operation of high-speed railway EMU.Because the EMU Depots of whole railway are placed with the purpose of servicing the local railway network,the construction of Chengdu EMU Depot will improve the EMU maintenance status of railway network and will fill the gap of EMU maintenance in the southwest region.This paper describes the design of Chengdu EMU Depot about its position selection, functional localization and its scale on the basis of the previous layout study of the routes,houses,roads, maintenance equipments and so on.As a result of the design,longitudinal and staggered type of layout was used in general plan,dispersed and standardized type of layout was used for maintenance workshops, double rows of tracks were located in front of the maintenance workshop and so on.It is estimated that the EMU maintenance efficiency would be increased and the project investment would be reduced with this design.
