“…Multiple efforts have been made to evaluate the so-called UUS resources, including physical space, geothermal energy, groundwater, and geomaterials. Some works, principally those from the Deep City Project [4,26,27,126,127], consider the four UUS assets comprehensively, while others deal with only one or two (mostly on physical space [128][129][130][131]) of the four UUS assets. The recent work of Price et al [132] incorporated the UUS asset of space continuum into the framework of ground-use optimization.…”

The utilization of urban underground space (UUS) offers an effective solution to urban problems but may also negatively affect urban development. Therefore, UUS development needs better concerted guidelines to coordinate various urban systems and the multiple components of the underground world. Sustainable Development Goals (SDGs), which should be viewed as important yardsticks for UUS development, do not explicitly mention urban underground space, although many of them are affected by both the positive and negative consequences of its development. To fill this gap, this review lays the foundations of relevant UUS concepts and uses exemplary cases to reveal that 11 out of 17 SDGs can be linked with UUS uses. These linkages also manifest that land administration, integrated planning, architectural design, and construction technology are critical dimensions for increasing the contributions of UUS to the realization of SDGs. To achieve multi-disciplinary synergies among these four critical dimensions, a collaborative approach framework based on spatial data infrastructure is required. Thus, this work provides academics and practitioners with a holistic view of sustainable UUS development.

“…e subjective weights for evaluation indices are determined based on the FAHP proposed by Chang [43]. In FAHP, the triangular fuzzy number (TFN) in Table 2 is recommended to represent the relative importance scale between objects [30,44,45].…”

“…irdly, the weights of evaluation indices in each comparison matrix were calculated fowling the FAHP. As the FAHP has been recorded in literature [33,44,45], the weight calculation process is omitted in this research and only the calculation results were presented in Tables 3-4. Finally, the global weights for all the evaluation indices were synthesized and presented in Table 5.…”

The stability of ground surface along tunnels in karst terrain is influenced by complex factors, among which the karst features are the significant ones. Under the influence of karst, the ground surface along tunnels is very easy to collapse, thus causing great casualties and economic losses. To provide guidance for maintaining the stability of ground surface along tunnels, an analysis system is proposed for assessing the stability of ground surface along tunnels in karst terrain based on an improved fuzzy comprehensive evaluation. Based on the case analysis of ground collapse along tunnels in karst terrain and the review of the related researches, the evaluation index system for ground surface stability assessment was established. The ridge-shaped membership functions were constructed to calculate the membership degree for the evaluation indices. The comprehensive weighting method combining the Fuzzy Analytical Hierarchy Process and correlation analysis was applied to determine weights for evaluation indices. And the ground surface stability level was recognized based on the maximum membership principle. The proposed assessment system was applied to assess the ground surface stability along the tunnels of Guiyang Metro Line 1, and the assessment results agreed well with the regional ground collapse history, verifying the effectiveness and reliability of the assessment system. Combining with the assessment results, a series of measures were conducted to promote the ground surface stability before tunnel excavation. This system provides a valuable tool for assessing and guiding to improve stability of the ground surface along tunnels in karst terrain.

“…Pairwise comparisons by experts determined the relative importance of each criterion. Lu and colleagues [29] also evaluated geological suitability for underground construction referring to expert opinion on geotechnical properties, geological structure, geomorphology, hydrogeology and adverse geological conditions. Their case study of the Wuchang Railway Station mapped suitability values according to the depth at which development was forecasted.…”

“…The method used in the Qingdao study includes distributions of land uses, population densities, transit networks or property status, but these are understood as indicators of possible demand [26]. Lu and colleagues [29], in their rail station case study, only evaluate geological suitability, independently of the station's urban context. The urban form is not only a passive source of demand, but also supplies a particular potential that is both latent and actual.…”

Underground Potential for Urban Sustainability: Mapping Resources and Their Interactions with the Deep City Method

2016

Abstract:In the process of urban growth, the underground is often only addressed once all surface alternatives have been exhausted. Experience shows that this can lead to unforeseen conflicts (e.g., subsidence, groundwater pollution) and to lost opportunities (e.g., combined geothermal systems and building foundations or recycling of excavation materials). One challenge is how the underground potentials are assessed by urban actors; data collection, analysis and visualization for the different resources are often conducted in separate disciplinary corners and administrative divisions. This paper presents a mapping method developed within the Deep City project at the Swiss Federal Institute of Technology in Lausanne (EPFL) and its application to San Antonio, Texas. San Antonio is interesting in its lack of major underground infrastructure and its few means and political support for short-term underground development. We will specifically look at the production of a series of interaction maps, an original mapping strategy that is complementary to the resource potential maps we have produced in prior work. After situating this research within larger theoretical and philosophical questions, we will show how mapping the combined potentiality of underground resources can serve as a compass for future interdisciplinary discussions that address the urban underground as a source of opportunity, rather than as an afterthought.
