JOURNAL FREE ACCESSShin-Yamamoto dam located near field of 2004 Niigata-ken Chuetsu Earthquake sustained serious damage such as large settlement and liquefaction. The dam is a 42.4 m high fill dam with a semicircular dam-axis, constructed in 1990. In-situ micro-tremor measurement on the dam followed by 2-D and 3-D FEM analyses were conducted to find vibration characteristic of the dam, and causes of the earthquake damage.View full abstractDownload PDF (2779K)

JOURNAL FREE ACCESSThe Sashikubo dam is a rock-fill dam, being constructed by Aomori prefecture, whose foundation on the right side bank is a thick Quaternary formation. The geological formation shows high permeability, but it was found that ordinary grouting works are not applicable due to the geological characteristics. This paper will introduce a course of study on selection of foundation treatment, best suited for unconsolidated foundation of Sashikubo dam. The first alternative was to construct concrete underground continuation wall; however, it was changed to soil-cement underground continuation wall, which is less costly and will acclimate with the soils.View full abstractDownload PDF (1372K) -

JOURNAL FREE ACCESSThe anchor technology is spreading as an effective reinforcement method of the dam body worldwide and attracts attention at the economy and the earthquake-resistance as the occasion demands. In this paper, we mention the latest situation of the anchor technology and introduce some representative Japan's and overseas examples.View full abstractDownload PDF (4828K) -
Revision of Strong Motion Records at Kasho Dam during the 2000 Western Tottori-Prefecture EarthquakeNobuteru SATO, Hideaki KAWASAKI, Tatsuo OHMACHI2007 Volume 17 Issue 4 Pages 295-304

JOURNAL FREE ACCESSDuring the 2000 Western Tottori-prefecture earthquake, strong motion records showed 531gal at the inspection gallery and 2051gal at the dam crest of Kasho Dam. The strong motion records are greatest seismic motion in Japan. In this report, the difference of the direction of the seismograph at Kasho Dam was inspected there, and the direction was revised. The response characteristic of the dam body was revaluated. Moreover, the Kasho Dam was reinspected, and the cautions place at dam special inspection after earthquake was indicated.View full abstractDownload PDF (1592K)
