城市中心区深层地下空间利用规划关键指标参数优选量化及准则研究

The state has clearly pointed out that it is a strategic science and technology issue for "marching into the deep of the earth" which must be solved. The urban spatial resource constraints and the progress of underground construction technology have made it possible and reliable to utilize deep underground space. Moreover, as the development model of urban deep underground space is so much different from that of medium and shallow underground space with historic top-down development, it is urgent to understand its rules for scientific planning. This research project try to make it clear what is deep underground concept. Through planning benchmarking of 12 typical large cities both at home and abroad, the relevance among the deep underground space use, the cities, the urban medium and shallow underground space use and the progress of construction technology are gotten by the idea of big data with relying more on correlation and less on causation. Further, three models with long term goal-oriented (space, transportation and environment) for deep underground space use are proposed. In order to test these ideas, we will put them in practice on selected two typical urban centers: one is an old town, and the other is a new city, and the model and guidelines for deep underground space are gotten. Based on the above results, three types of key and feature indicators and parameters are selected, and the threshold value of the above some indicators and parameters are expected to get. The above results will provide a scientific and effective basis for the urban deep underground space development.

国家已明确“向地球深部进军”是必须解决的战略科技问题，而城市面临的空间资源约束等问题及地下建设技术进展使得城市深层地下空间利用成为可能和现实，更由于不同于甚至迥异于目前中浅层地下“自上向下”为主的利用方式，弄清其科学规划规律尤为迫切。项目首先界定城市中心区深层地下空间概念，通过对国内外12个典型大城市的规划对标，借鉴大数据“重相关不重因果”的思想，分析得到深层地下空间利用与城市、中浅层地下空间以及建设技术进展等三类指标的对应关系；进一步，建立基于三类长远目标（空间、交通和环境）的利用模式微元，并结合新、老城市中心区进行模式组合设计检验反馈，得到深层地下空间利用模式与准则；在此基础上，重点对适宜条件、利用模式与准则等三类关键特性指标参数进行优选，通过建模、数据分析及仿真模拟等方法比较分析，期望得出若干关键规划基础指标参数阈值，从而为城市深层地下空间利用提供科学有效的理论支撑。
