城市地下空间资源探测评价技术体系研究

Study on exploration and evaluation technology system of urban underground space resources

城市地下空间资源开发利用在城市高质量发展中发挥着关键作用。通过梳理城市地下空间资源探测评价研究现状和面临的主要问题,提出建立城市地下空间资源探测评价技术体系的建议。突破传统地质工作理念,把城市地上、地面、地下一定深度国土空间作为整体,在立体、多维、多尺度、多介质空间下,认为城市地下空间资源全要素可分为全空间地理要素信息、全功能构筑物要素信息和全要素地质信息;通过空间地理测绘、钻探、地球物理探测、高光谱岩心扫描、分析测试等探测技术和三维动态建模技术,建立城市地下全空间地理信息数据库、全功能地下设施数据库和全要素地质信息数据库;通过城市地下空间资源要素评价和要素重要性评价,实现对城市地下多种地质资源协同开发评价和城市地下空间功能分层开发强度阈值评价。该文提出的全要素分类-全要素探测-全信息集成-全资源评价技术体系,可为城市地下空间资源开发利用全生命周期提供支撑。

The exploitation and utilization of urban underground space resources(UUSR)have played a key role in urban high-quality development.The viewpoint of establishing the technical system of exploration and evaluation of UUSR is put forward based on the analyses on the current research situation and main problems emerged from both fine exploration and resource evaluation.Breaking through the traditional concept of geological work,the study takes the urban aboveground,ground space and the underground within a certain depth as a whole,and divides the full factors of UUSR into whole space geographic element information,full-function structure element information and full-element geological information from multi-dimensional,multi-scale and multi-media space.The database of each information above could be established through spatial geographic mapping,drilling,geophysical exploration,hyperspectral core scanning,testing and three-dimensional dynamic modeling technology.The evaluation on collaborative development of urban underground geological resources and the intensity threshold evaluation on layered development of urban underground space functions could be operated based on the evaluations of UUSR elements and the elements'importance.The technical system of full factors classification-full factors exploration-whole information integration-whole resources evaluation proposed in this paper can provide support for the whole life cycle of UUSR development and utilization.
