Research Division

Department of Geotechnical Engineering Research Research
The Department of Geotechnical Engineering Research develops advanced construction technologies that optimize the foundations that determine the integrity of structures and tunnels, and studies methods of preventing and reducing the severity of accidents caused by engineering and natural factors, such as underground pipeline ruptures, subsidence, and soil liquefaction. It creates new industries through advanced developments and integrations in areas that include automated subterranean development using tunnel boring machines (TBM), renewable energy (offshore wind power plants, geologic storage of carbon dioxide), and advanced materials (biopolymers, high-strength materials). Its efforts in the field of smart construction technology include the development of digital quality inspection procedures applied to automated construction equipment, and it is also focused on creating technology for the smart development and maintenance of infrastructure and for pioneering new environments in the ocean and below the ground. The mission of the Department of Geotechnical Engineering Research is to research and develop building safety technology that minimizes damage and harm in the event of ground failures, and create new environments for our habitation.
