| Outline of Final Research Achievements |
Large earthquakes cause the liquefaction of the ground and further damage the detached houses such as settlements. In order to reduce these damages, in this study, we developed a numerical scheme by particle method called smoothed particle hydrodynamic method that can predict the settlement of buildings using low-cost and feasible ground survey results. Furthermore, model shaking table tests and field surveys were conducted to grasp the damage situation and its mechanism. From the comparison of those results, it was possible to roughly predict the settlement and inclination of the structure due to liquefaction by this proposed method.

| Academic Significance and Societal Importance of the Research Achievements |
本研究課題における解析プログラムの開発および簡易地盤調査によって，戸建て住宅が抱える特有の問題を解決した液状化による構造物の沈下や傾斜を推定する手法を提案することができた．戸建て住宅における液状化被害が予測でき，設計者による施主に対する高精度な情報提供の実現性も見えている．現在，排水ドレーン工法や浮き基礎工法などの液状化対策工法の開発にも本手法が取り入れられており，今後の液状化対策の普及に大きく貢献するものと推察される．
