A Methodology for Comprehensive Quality Evaluation of Underground Space

Abstract

Underground space resources are important for the purposes of urban sustainable development and are a significant means by which to realize three-dimensional urban development. A reasonable and scientific evaluation of underground space resources is the foundation for the rational use of land resources and urban planning. On the basis of the geological conditions used by preceding researchers, this study adds the analysis of two influencing factors of social and economic value, alongside existing facilities and protection needs. The evaluation index is quantified and the comprehensive quality evaluation system of underground space resources is constructed. Finally, taking the 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 as areas to actively develop underground space, whereas the Qianhai and Houhai areas are recommended to be used with caution in the development and construction of their underground space. In addition, this study also provides a reference for the purposes of underground space planning in the Nanshan district of Shenzhen.
