Outline of Final Research Achievements

The earthquake-resistance of soil structures such as embankments of river and reservoir has been insufficient, and the development of economical aseismic technology for soil structures has been required. In this study, new structural and material types were examined for the purpose to toughen soil structures. As a measure to improve seismic behaviors of soil structures, the partially reinforced embankment was proposed based on a series of shaking table model tests and numerical analyses. In addition, development of ductile composite geomaterial was conducted considering utilization of low-use materials such as reclaimed plastic, bamboo fiber, tsunami deposit soils, reclaimed plastic and others.
