| The creep ratio, which has been applied as a measure to prevent piping failure in designing embankments, has been originally proposed for the protection of masonry or concrete dam from piping along the boundary surface between the foundation soil and the bottom of the structure. In this study, it has been investigated whether this creep ratio could be applied for the earth embankment through the model test and we reevaluated the required creep ratio in the present design criteria. Based on this research, it was concluded that a piping failure would always occur within the embankment body and not through the boundary surface between the embankment and foundation. Therefore it could be said that the present design criteria are illogical to determine the design creep ratio according to less permeable soil no matter whether the soil forms embankment or foundation. |
