| Outline of Final Research Achievements |
In the conventional experimental technique of geotechnical engineering, there was no way to visualize the actual behavior of the pile foundation and the surrounding ground continuously in time. In this research, we conducted confirmation of the applicability of a new experimental technique called the refractive index matching method.
A pile loading visualization tests were conducted based on the obtained knowledge, and the interaction mechanism between the pile and the ground was examined. The actual behavior of pile in the ground during loading was observed, and the range of influence on the ground during loading was visualized.

| Academic Significance and Societal Importance of the Research Achievements |
従来の地盤工学における模型実験技術では，時々刻々と変化する地盤内部の変形現象を時間的連続的に捉えることが難しかった．一方，屈折率整合法では連続した情報を時間的に連続で得ることができる新しい実験技術である．
本研究の成果をさらに発展させることで，杭基礎と地盤の変形挙動が定量的に予測できる可能性があり，適切な杭基礎工法の選定，合理的な設計につなげることが可能となる．
