Abstract

Among the dams managed by Japan’s Ministry of Land, Construction and Transport, Shin-Katsurazawa Dam is the first dam to be renewed by coaxially raising the embankment of an existent dam. Raising the embankment of an existent dam that is in operation involves various problems that are different from the ones involved in constructing a new dam, such as evaluation of the foundation base rock and integration of concrete of the old and new dam bodies. The technical features of Shin-Katsurazawa Dam as a coaxially raised dam and measures taken to solve the various problems involved are presented.
