Postconstruction Deformations of Rockfill Dams

Abstract

Postconstruction deformations of some rockfill dams with a slightly inclined or central till (moraine) core are presented. Although deformation still continues, even 30 years after dam construction, for all practical purposes the settlement could be nevertheless considered to cease 36 months following the end of construction. The crest settlement reflects the core compression, which is relatively low, while the downstream rockfill shoulders exhibit much higher settlements. The maximum settlement expressed as a percentage of height (%
