地下敞开式车辆基地设计要点

Main Points in the Design of Underground Open Metro Depot

以无锡地铁2号线青龙山停车场设计为案例,分析了地下敞开式车辆基地的特点和限制性因素,对车辆基地的下凹区范围、出入段场线与车场线路坡度、下凹区与外部道路的连接、下凹区排水、大库屋顶与周边道路的衔接、消防设施等关键要点进行研究,提出了地下敞开式车辆基地设计要点原则和设计注意事项。研究成果可为类似地铁车辆基地的设计提供参考。

The design of Qinglong Hill Stabling Yard on Wuxi metro Line 2 is introduced,the characteristics and restrictive factors of underground open metro depot are analyzed,the lower concave area of depot,inbound and outbound siding and track gradient,road connection,drainage system,the connection between storehouse roof and the surrounding roads,fire protection facilities and so on are studied in depth. Principles and consideration for the design of underground open metro depot are proposed,so as to provide a reference for the design of similar projects.
