Then, the repair work was carried out to prevent the further disaster. When the dam was removed as a part of the repair work in 1998,veins of chemical grouting conducted in l995 appeare on the surface of excavated dam. This report discusses the effect of chemical grouting associated with material properties of dam, based on field-observed records such a the sketches and the photogiaphs.
