• Research Topics

  Soil-water-heat-chemical coupling issues related to geoenvironmental conservation

• Overview of the research

  This resarch focuses on coupled thermo–hydro–chemical (T–H–C) processes related to geotechnical environmental preservation, evaluating how temperature variations and chemical reactions influence soil permeability and stability. Hydraulic and chemical properties are obtained through permeability and batch tests, and combined with reactive transport analyses considering adsorption, dissolution, and swelling. This integrated approach clarifies contaminant migration and suppression mechanisms under various environmental conditions, aiming to establish long-term, sustainable ground environmental protection technologies.
