Nanjing underground space development planning construction area of 54 million square meters will be released on three levels to build "underground city" based on the rail transit network, the urban area of Nanjing will series (the city, Vice City, Metro) focus on the construction of underground space, the formation of "the overall structure of the four City, seven, many" three grade center the network of underground space; enhance the potential to optimize the main city, Vice City, the positive development of metro. A center (four City) – including Xinjiekou Gulou center, South Station – Honghua Airport Center, Hexi center, Jiangbei center. Encourage the underground public facilities scale, diversification, integration, high strength development, establish smooth comfortable public underground pedestrian system, form a network of underground city. At the same time, to encourage the use of underground pedestrian crossing and various underground pedestrian road connectivity, commercial, service industry development channel and a variety of formats, enhance the vitality of the pedestrian system. Two grade Center (seven pieces) including Hunan Road, Binjiang, Confucius temple, Shimonoseki Dongshan deputy city center, deputy city center, Xianlin Xiongzhou center, Nanjing North station. Planning clear, two grade center to encourage high strength, even the development of underground space, the establishment of distinct public underground connected trails, formation of functional composite underground commercial street. At the same time, the main underground walk on both sides of the road should be connected to the development of commercial channels, secondary roads as the use and transformation of the conditions, the appropriate development. Three grade Center (multiple points) including the commercial center of Xianlin University City, Maigaoqiao, North Bridge, Longjiang and other regions, and the NanJing Railway Station, airport and other transportation hub areas, the formation of underground public space to the underground complex point. At the same time, its underground pedestrian facilities combined with its location and flow characteristics, can be the appropriate channel business development. According to the principle of comprehensive evaluation and social demand analysis of underground space resources in Nanjing, the development and utilization of urban and rural areas in various areas are proposed. Among them, including the core of key ecological function zones, a drinking water source protection area and land area, groundwater (including hot springs) reserve, Yangtze River flood affected areas, in addition to the underground rail transportation, underground roads and other infrastructure by linear, are prohibited the development and utilization of underground space area. The source region of the Yangtze River including two levels of drinking and land, Water Conservation District, Zijin Mountain, general mountain, Qixia mountain and other key ecological function buffer, prohibit the development and utilization of large-scale underground space principle, restricted development area for underground space. Plan for a 8 underground bus station in the future, with the key area of underground space, city center and transportation hub areas, planning proposals set 8 underground bus station. According to the plan, the future of the city’s underground space in Nanjing is divided into shallow (0 ~ -15.0m), middle (-15.0 ~ -40.0m), deep (-40.0m below) levels. During the planning period to encourage the development of shallow, moderate development of the middle, special circumstances can be required, the conditions for deep development and utilization. Planning tunnel 9 reserved tunnel from the opening of the important nodes of the main line of traffic and ease the focus of the development of traffic conflicts from the perspective of the proposed planning of the underground road 3.相关的主题文章:
