- many large-scale underground energy storage caverns in response to rapid
industrial development. In this period, rock mechanical engineers in Korea gained valuable experience in developing underground
space technologies. A briefdescription ofunder ground projects, including oil and gas storage and pumped storage power plants,
is presented. Mechanical and hydrological stability analyses ofthe storage caverns are also introduced. These analyses were
conducted using a finite-element method, back analysis, rock block analysis and fracture network analysis. In each analysis, the
rock mass around the caverns is modeled as a rigid body, elastic, visco-elastic, visco-plastic or elasto-plastic porous medium.
