| 内容記述 | Many small earth dams were damaged induced by the 2011 off the Pacific coast of Tohoku Earthquake. 3 dams were totally collapsed. The reserved water ran off the downstream area and killed 8 people. In this paper, conditions of each damaged dams and the features of damages were described. Longitudinal cracks on the crests and sliding failures on the upstream slopes were mostly often observed and falls of wave protection wall on the upstream slopes enlarged the damages. The water levels of the dams when the earthquake happened were full because it was just before the irrigation season and it is one of the causes of large damages. In order to prevent breaches of the damaged dam after earthquake, emergency measures such as investigations of the depth of the cracks and controls of the reserved water levels were performed. We proposed a method of countermeasures for small earth dams against future earthquakes. Year of past countermeasures and damaged area in case of dam breaches are important factor to select dams which need countermeasures among 210,000 dams. After that, soil strength of an embankment using boring or sounding should be decided for a stability analysis or Newmark analysis. Finally, we can decide small earth dams which need disaster mitigation. |
