南京江北新区中心区地下空间一期项目地下共享通道方案设计研究

Study on Scheme Design of Underground Shared Passage in Nanjing Jiangbei New District Central Area Underground Space Phase I Project

摘要:

随着我国城市CBD核心商务区的建设开发，如何合理调配CBD范围各车库的空余车位，使停车资源的利用率最大化是亟待解决的问题。在南京江北新区中心区地下空间一期项目设计研究中，通过设计地下小汽车环形共享通道，以联系并整合区域内的地下停车资源，提高车库的使用效率。利用外围与市政道路衔接的出入口，快速分流部分进出地下车库的小汽车交通，从而减少地面的道路交通压力，提高CBD的交通服务品质。提出了“一环两联络”环形方案与“一线六联络”树形方案共两种设计方案，并从交通功能、连通地块数、车库共享工程、实施工序、工程造价等方面对两方案进行对比分析。分析结果表明，“一环两联络”环形方案能更有效地联系并整合区域内的地下停车资源，提高车库的使用效率。

Abstract:

With the construction and development of urban core business districts (CBD) in China, how to rationally allocate the vacant parking spaces in various garages and maximize the utilization of parking resources is an urgent problem to solve. In the study on the design of Nanjing Jiangbei New District Central Area Underground Space Phase I Project, a circular shared passage for the underground cars is designed, and the underground parking resources are connected and integrated in order to improve the service efficiency of the garage. At the same time, the entrances and exits connected to the municipal roads are used to quickly divert some car traffic entering and exiting the underground garage, thereby reducing the road traffic pressure on the ground and improving the traffic service quality of CBD. Two design schemes of "one-ring two-connection" ring scheme and "one-line six-connection" tree-shaped scheme are proposed, and compared and analyzed from the aspects of traffic function, connected land number, garage sharing engineering, implementation process and engineering cost. The analysis result shows that the "one-ring two-connection" ring scheme can more effectively connect and integrate the underground parking resource in the area and improve the service efficiency of garage.
