STUDY ON A TECHNOLOGY DEVELOPPED TO RESTORE ROAD EMBANKMENT DAMAGED IN NATURAL DISASTERS USING GEOSYNTHETICS

Abstract

Five years have passed since the disaster by the Great East Japan Earthquake of 11 March 2011. While restoration revival projects at the damaged area were being in progress, a series of large-scale natural disasters took place consecutively, including heavy rain at Kanto-Tohoku areas in September 2015 and an earthquake at Kumamoto in April 2016.As quickly as possible recovery from the breakdown of the transportation system caused by disasters is required. In this research, we confirm the applicability of the restoration technology using large sandbags and grid reinforcements by real scale experimental test.
