Outline of Final Research Achievements

This research project has aimed to develop geotechnical technology for disaster road restoration and has conducted four main tasks: 1) development of deployable geocell reinforcement for disaster road restoration, 2) Physical modeling of advanced reinforcement technology considering the damage situation, 3) Material testing on reinforcement materials with reducing environmental impact, 4) Proposal of performance evaluation method contributed to crisis management. Geotechnical technology for road restoration was proposed, and the test results provided the basic framework for the ground deformation prediction model and performance evaluation method.

Academic Significance and Societal Importance of the Research Achievements

道路の早期復旧や本復旧までを見通した復旧技術の構築は非常に重要であり,急務の課題となっている.そのような中で,本研究は,常時の備えから緊急復旧,本復旧などを見通した地盤技術の構築を行っている.復旧技術についても,道路の路盤から舗装部までを対象にした技術に加え,道路盛土の崩壊を想定した復旧技術を提案している.実験結果より,復旧技術の高度化を図るとともに,補強効果の評価法を提案している.道路の早期復旧技術の進展,地盤補強技術の適用性拡大という両方の分野において,新たな知見を提示できたと考える.
