This paper reviews the creep ratio concept suggested by Lane (1934) and added new case histories to expand his database. Lane (1934) selected conservative values of safe creep ratios because of the small number of dam failures in his database, which is prudent. The safe creep ratios recommended in this paper for “Gravel and Sand”, “Boulders, Gravel, and Sand”, and broadly-graded soils are believed to be a conservative interpretation of the available data. As Lane’s recommended values appear to be somewhat subjective, considerable engineering judgment is recommended in designing a dam for safety against piping, and Lane’s values are a starting point for design, rather than values for a final design.
