The Geo-Environment Laboratory conducts research focused on the interaction between soil structures—such as river levees, embankments, and natural slopes—and water, aiming to realize disaster-resilient social infrastructure. In recent years, seepage failure of embankments and slope failures caused by torrential rains and earthquakes have increased. We are working to elucidate the failure mechanisms and enhance safety using numerical analysis and field observations. 

　Another key theme is evaluating ground deformation caused by snowmelt infiltration and freeze-thaw cycles in snowy, cold regions. Furthermore, we are developing slope failure prediction models utilizing DEM, geological, and rainfall data, and advancing methods for assessing the integrity of earth structures incorporating AI technology. Additionally, related to geological disposal of radioactive waste, we evaluate the mechanical and swelling properties of bentonite buffer materials and predict long-term behavior through coupled analysis (THMC analysis) addressing interactions with rock formations. 

　Through these research efforts, we aim to enhance regional disaster resilience and contribute to building safe and sustainable social infrastructure.
