Abstract
We were investigated the several examples of the old small earth dams that improved the safety and prevented the leakage of the existing embankment by applying the rehabilitation technique for old embankments using the cement-stabilizeed muddy soil. This paper presents a general considerations of the factors to be considered in designing to improve the safety and to prevent the leakage of a old embankment dam. We concluded that it is important for the dedign of zoning pattern to rehabilitate the old small earth dam to minimize the strength gap between the additional embankment constructed by the cement-stabilized muddy soil and the existing embankment.
