Description

 Since we have concerned about the occurrence of large earthquakes in Tokyo area and Nankai trough, we are examining seismic measures for special levees in the city center. However, the detailed research of the special levees behavior induced by earthquake has not been promoted enough until now. The seismic countermeasure of special levee is designed by level 1 ground motion now. In this study, damage to special levees in the 2016 Kumamoto earthquake was compared to past earthquakes. We analyzed effects of earthquake motion on damage to special levees were investigated using observed motion recorded near the damaged special levees. Based on these results, problems of seismic design for special levee were pointed out.
