The Outardes 2 Concrete-Faced Rockfill Dam

by O. Dascal,



Document Type: Proceeding Paper

Part of: Concrete Face Rockfill Dams?Design, Construction, and Performance

Abstract:

The main dam of the Outardes 2 development consists of a rockfill embankment, built against an old water-retaining structure, and faced with an upstream concrete membrane. The interface problems with the bedrock, the new spillway and the old structure in the riverbed represent interesting aspects of the project. The introduction of a new time and cost-saving concreting method also contributed to some of the innovative solutions applied. Operated since 1979 under relatively severe climatic conditions, the dam has exhibited a very good behavior to date.
