“…One of the most important steps in the site selection process is assigning a value or weight to each factor or information layer (Hassanpour et al 2017). Veress (2020) presented hierarchical classi cation of the Earth's postgenetic karsts and described karst types (Veress 2020).…”

This study has been carried out with the aim of identification of areas of extensive karstification and consequently groundwater resource potential carbonate rocks in Iran considering the role of the chief factors affecting karst water potential. Accordingly, 25 different data layers where interrogated in a GIS platform. Subjective karst map was developed on the basis of what is considered to be a proper combination of these factors. The most important parameters are categorized to three driving factors include chemical, physical, and hydrogeological factors. Thematic map of each parameter was prepared using geographic information system (GIS). Measuring the rate and weight of the maps was performed using analytical hierarchical process (AHP), respectively. The final output map showed different zones of groundwater prospective potential, which was divided into five grades. According to the results, of the total area of 174049 km2 of carbonate outcrops in Iran, 10.5 % belongs to grade 1 (very high degree), 15 % to grade 2 (high degree), 24.5 % to grade 3 (medium degree), 29 % to grade 4 (low degree), and 21 % grade 5 (very low degree) of karst water potential. There is a significant karst water source in the southwest, north, and north east of Iran. The highest grade is belonging to the Kopet-Dagh zone in northeast of Iran.

“…This approach is also recognized as a reserve bank with high global strategic security (State Council of the People’s Republic of China, 2013). The basic principle of underground oil storage in unlined rock caverns is that the groundwater pressure surrounding the caverns should be higher than the storage cavern pressure, and the groundwater should flow into caverns to prevent oil leakages (Hassanpour et al., 2019; Lin et al., 2016). The water-sealing effect and rock mass stability are two key scientific problems for the construction of underground water-sealed oil storage caverns (Shi et al., 2018; Zhuang et al., 2017), especially the relation between rock mass stability and the caverns’ stability.…”

The stability of underground water-sealed oil storage caverns is of great importance for safe excavation and operation. To analyze the scope of the failure zone and underground cavern stability accurately, a new method was developed that integrates the rock tunneling quality index Q-system and stability graph method with 3D laser scanning and numerical simulation. The point cloud data were obtained by 3D laser scanning, and the cavern model was built by using DIMINE software, which directly shows the 3D shape of the cavern. The rock mass physical and mechanical parameters and the corresponding stability coefficients were obtained based on Q-system and stability graph method. The plastic zone distribution and deformation characteristics of surrounding rock were analyzed through numerical simulation. Then, the corresponding relationship between caving zone and plastic zone was determined by comparing the numerical simulation results with the 3D laser scanning contour. The new method provides a reliable way to analyze the stability of the underground water-sealed oil storage cavern and also will helpful to design or optimize the subsequent support.
