ABSTRACT
During the 2016 Kumamoto earthquake, which caused two seismic intensities of seven for two days, numerous severely damaged infrastructures were constructed in the vicinity of active faults. Most of these structures have now been reconstructed and are currently in service. In such areas, it is necessary to consider the minimization of the damage as much as possible in the event of future seismic motion or ground surface displacement. In addition, if the deformed structure can avoid collapse, it is necessary to evaluate its integrity for its use. In this study, surveys were conducted on two types of structures: a steel strip reinforced soil wall and an expanded polystyrene lightweight embankment located near active faults that was damaged during the Kumamoto earthquake. The methods were used to evaluate the integrity of the structures and the policies and methods of reconstruction.
