Rational geotechnical modeling and elasto-viscoplastic numerical procedure have been developed to assess the long-term large deformation and stability of the soft soil deposits that are situating along metropolitan bay area. The research activities are also directed towards developing a sophisticated tool for sounding, such as “radio-isotope cone penetrometer” that can precisely detect the wet density as well as natural water content to evaluate the quality of soft soil deposits. Urban geoinformatics is one of the newly developed research field in which geoinformatics database plays a significant role to assess the fragility of local ground and assist for regional geo-disaster mitigation. In addition, archaeological geotechnics is a recent matter of concern to restore and conserve various historical geo-remains with authenticity.

不飽和土の水分・熱移動と変形に興味があり,これに軸足に置いて,古墳などの歴史的な地盤構造物の自然災害による損傷メカニズムの解明と保全手法の構築に応用しています。遺構では,地震や降雨による力学的安定性の低下や,埋葬空間の温湿度環境に起因した汚損といった問題が複合的・連鎖的に生じています。これらの損傷を不飽和土の変形,浸透,熱伝導の問題に変換し,実験および数値解析による手法を用いて,損傷に至る過程を定量的に説明し,力学的根拠に基づいた対策を提案しています。水分移動が激しく,低拘束圧条件下にある地表の遺構では,従来の地盤工学ではあまり研究されていない課題に度々直面します。これらの課題を追究し,地盤工学の知見を蓄積すると同時に,文化財保全を通じて地盤工学の活用の拡大に貢献することを目標にしています。

I am interested in hydrothermal transfers and deformation of unsaturated soils. The knowledge of unsaturated soil mechanics is applied to understand the mechanism of damage caused by natural hazards and develop restoration methods of geo-relics such as tumulus mounds. Multiple and chain-reaction problems occur in geo-relics; reduction of stability due to earthquakes and precipitation, and deterioration of burial chambers caused by hydrothermal environment. These problems are translated into the problems of unsaturated soil mechanics (e.g., deformation, seepage, heat conduction). The damage processes are quantitatively analyzed using experimental and numerical methods. Understanding the mechanism of damage enables us to propose effective countermeasures. We often face problems that have not been discussed a lot in previous studies in geo-relics under active water transfer and low confining pressure conditions. We contribute to accumulate knowledge of geotechnical engineering by studying these problems, and expand the field of study through preservation of cultural heritages.
