Abstract: The leakage is a comprehensive reflection of face rockfill dam operation state, and leakage evaluation is an important issue related to engineering safety. For 37 domestic and abroad face rockfill dams completed during 1971~2009, more than 78 m in height, engineering analogy of leakage was conducted by homogenizing the face area. The criteria could be roughly drew up as follow: the face average leakage within 12×10^-4 L/(s·m²) indicates a small amount of leakage; (12~24)×10^-4 L/(s·m²) indicates moderate amount of leakage; and more than 24×10^-4 L/(s·m²) indicates that the amount of leakage is too large. The statistical criterion could be a reference for similar dams.
