地震動が外水位上昇を受けた堤体の崩壊挙動に及ぼす影響に関する縮尺模型実験

抄録

In recent years, damage to levees due to floods after the earthquake has been reported. However, there are few studies on the relevance between the magnitude of the earthquake and the level of the embankment during the flood.

In this study, a scale model experiment was conducted to clarify the influence of the difference in maximum acceleration on the rising behavior of the water level in the levee and to clarify the penetration collapse behavior. Based on the experimental results, the permeability of levee varied depending on the magnitude of maximum acceleration. In addition, the amount of embankment deformation due to aftershocks may be affected by changes in permeability due to the main shock.
