Contribution of environmental geotechnics for disaster recovery

Abstract

The 2011 earthquake off the Pacific coast of Tohoku was the source of several geoenvironmental issues in the eastern region of Japan. Among these issues, treatment of disaster debris and utilization of treated materials in geotechnical applications is presented in this manuscript. Use of the treated disaster debris for the recovery of infrastructures has been conducted at the disaster affected areas, in particular at areas that suffered from subsidence. Current status of characterization, standardization, and strategic utilization of the recovered soils obtained from the disaster debris is also presented in this paper. This includes the contributions by the Japanese Geotechnical Society.
