| Outline of Final Research Achievements |
The objective of this study is clarifying the mechanism of ‘compaction’ in the framework of unsaturated soil mechanics. We focus on the roller compaction, which is used for in actual earthmoving construction. Here, nonuniformity of compaction degree within earth structure constructed by roller compaction was investigated through model tests and numerical simulations. Moreover, behavior of infiltrated rainwater in small embankment models monitored by various sensors was compared with unsaturated seepage theory. The electrical prospecting was also conducted on these models to investigate its applicability.

| Academic Significance and Societal Importance of the Research Achievements |
盛土やアースダムといった陸上の地盤構造は，「締固め」施工によって造られるものの，これまで「締固め」メカニズムについて力学的な説明が十分ではなかったため，実施工では経験的手法を用いざるを得なかった．本研究では，「締固め」の力学的意義を明らかにするとともに，数値計算手法を提案しており，設計時の施工シミュレーションの可能性を示している．これによって使用材料に応じた適切な締固め手法を模索することができるようになると考える．
