“…Distinct from the urban surface, UUS is fragile and vulnerable to damage during the development and utilization due to its geological features (Zhu et al, 2016), which would experience permanent and irreversible changes once utilized. Also, irrational development often leads to irregular arrangement of underground structures, which could cause safety issues, such as geological hazards like collapse and seepage (Tan et al, 2021).…”

Urban geological modeling (UGM) is a fundamental approach for the visualization of underground space and recognition of complex geological conditions of a city. Previous UGM studies, with the assumption of homogeneous geological characteristics, have resulted in deviated modeling properties due to the negligence of parameters with obviously different spatial distributions in lithologies. This study presents a case study of Guang’an city in SW China by using a sequential simulation interpolation (SSI) method that reflects geological heterogeneity by combining field surveys, topography, borehole data, geological profiles, and stratigraphic columns to establish a lithology distribution model in the study area. The geotechnical attribute model of the area of interest was established based on lithology to capture subtle variations in lithology due to obvious differences in geotechnical characteristics of clay, sand, mudstone, sandy mudstone, and shaly sandstone. This 3D model could provide a reference for the urban underground space master planning and future sustainable development of Guang’an city. In addition, this study also discusses the prospects and directions of urban geological modeling and provides a few suggestions for engineering in urban areas.

“…Then combined with the construction conditions on the ground of the downtown in Danyang city, they forecasted the development demand of underground space and pointed out in the conclusion that the development and utilization plan methods for underground space in small-and medium-sized cities should be guided by the overall development demand of urban space. Gu et al [20] through comparative analysis of the current three urban underground space prediction methods and their characteristics at home and abroad, including per capita demand, subsystems, and demand intensity, proposed a comprehensive forecasting method that combines the characteristics of multiple forecasting methods based on the actual conditions of the forecasted area. The new method can qualitatively correct the demand for multiple forecasting methods and rationally select a scientific demand value.…”

Under the background of the rapid development of urban rail transit in China, the development demand of urban underground space has also greatly increased especially in the rail transit station areas. In this paper, taking the high-speed railway station area of Xuzhou Metro Line 1 as an example, the underground space development demand evaluation is conducted by considering the principle of urban underground space stock planning, the local underground space development conditions, as well as the special planning of the local urban constructions. Using the Analytic Hierarchy Process (AHP), a specific weight indicator scale is employed after the rationality of different weight indicator scales being compared. And then the weight indicator of different function types, i.e., commercial, parking, road, etc., are calculated and laterly utilized to forecast the recent development demand of underground space in the station area. Moreover, the steps to forecast the underground space development demand in rail transit station area are proposed, which can provide a reference for the forecasting of underground space development demand in the urban rail transit station areas.

“…Many studies on geological suitability evaluation for underground space utilisation have been reported in recent years. The AHP (analytic hierarchy process) method is the most adopted approach [10][11][12][13]. Normally, the evaluation indexes are considered as two aspects.…”

Geological suitability evaluation of urban traffic underground space utilisation is an important basic work in urban planning, especially for soft soil areas. In this study, firstly, on the basis of analyzing the influencing factors of urban underground transportation space utilisation in soft soil areas, and considering factors such as topography, geotechnical properties, hydrogeology, and existing constructions, an evaluation index system was constructed. The index weights are comprehensively determined according to expert scores and literature research. Then, the evaluation index is quantified by AHP (analytic hierarchy process) method and the suitability of the study area was calculated by multi-objective linear weighting method according to the established evaluation model. Finally, taking Wenyi Road in Hangzhou as an example, using the established evaluation index system and evaluation model to carry out the application research of geological suitability evaluation of underground space utilisation. The research results can provide technical reference for the utilisation of urban traffic underground space in soft soil areas.
