研究目的: 轨道交通车辆段与综合基地是综合性极强，牵涉专业、部门、系统众多、接口关系纵横交错的市政工程之一，不同设计阶段，接口重点不同，如何把握关键接口、理顺接口关系，对整体工程质量、工程投资和建设工期有着重大影响。本文通过分析车辆基地工程特点，工程建设参与方相互关系，结合各设计阶段研究目标，以设计阶段为轴线，分析梳理各设计阶段对工程有重大影响的主要接口内容、接口目的、接口执行方式，提出了车辆基地接口管理流程和主要技术接口风险及防范措施。
研究结论: 轨道交通车辆基地项目设计，应根据各设计阶段研究目的，车辆基地工程对应设计阶段应达到的目标，重视接口清理、理顺接口关系、明确接口标准、抓住接口重点，把握接口风险防范措施。
Research purposes: The vehicle depot and integrated base of urban rail transit is one of complex and comprehesive municipal works which involves in many majors，departments，systems and cross interfaces． In the different design stage，there is the different interfaces to be stressed on． How to master the key interfaces and straighten out interface relations are crucial to the overall project quanlity，project investment and construction period． Based on describing the engineering features of the vehicle base，the relations among the constructors，the research objectives invarious design stage，taking the design stage as the axial line，this paper analyzes the main interface contents，theinterface goal and the interface execution way in the various design stages that have big impact on the whole project， offers the management process of the vehicle base，points out the risks of the main technical interfaces and puts forward the measures for prevention of the risk．
Research conclusions: The vehicle base of urban rail transit should be designed according to the research objectives in various design stages and the goals that should be achieved in the corresponding stages． Putting the interface in order should be strengthened，the interface relation should be straightened out，the interface standard should be clear and definite，the key points of the interface should be grasped and the measures for prevention of the interface risk should be mastered．
