DAMAGE DUE TO THE 2011 TOHOKU EARTHQUAKE IN THE GEOGRID REINFORCED SOIL WALL MONITORED SINCE 1995

Abstract

The 8m-high geogrid reinforced wall monitored since 1995 has been damaged due to the 2011 earthquake. The authors analyzed the seismic wave and investigated the damage. These activities are useful for developing the limit state design based on reliability design concept. This paper reports the seismic wave analysis result, investigation results on the base foundation and facing deformation, and results of seismic stability analysis based on the current design method developed by Public Work Research Center
