ABSTRACT

ABSTRACT: The Ishibuchi Dam is a dumped rock CFRD with height of 53 m, completed in 1953. During the Iwate-Miyagi Nairiku Earthquake in 2008, a seismograph installed on the crest of the Ishibuchi Dam, which was located 9.4 km from the epicenter, recorded maximum acceleration of 14.61 m/s2 horizontally and 20.70 m/s2 vertically. However, the concrete facing was largely unaffected, the water storage function of the dam was completely maintained, and the damage to the dam body and the appurtenant structures remained within a repairable range.
