A Methodology of Comprehensive Quality Evaluation for the Underground Space

Abstract

Underground space resources are very important for the purposes of urban sustainable develop Underground space resources are very important for the purposes of urban sustainable development and are an important way in which to realize three-dimensional urban development. A reasonable and scientific evaluation of underground space resources is the basis for the rational use of land resources and urban planning. On the basis of the geological conditions concerned by predecessors, this study adds the analysis of the two influencing factors of social and economic value, existing facilities and protection needs. The evaluation index is quantified, and the comprehensive quality evaluation system of underground space resources is constructed. Finally, taking Nanshan District of Shenzhen as an example, the evaluation of underground space resources is carried out. The results show that for shallow underground space, the comprehensive quality of underground space resources development in Nanshan District is generally high. Nantou, Nanshan, and Yuehai streets are recommended to actively develop underground space, and Qianhai and Houhai areas are recommended to be cautious in the development and construction of underground space. In addition, this study also provide reference for the purposes of underground space planning in Nanshan District of Shenzhen.
