Abstract
The core-foundation interface of the embankment dams requires particular attention during design and construction, and specific surveillance during operation. A deficient treatment of this area may facilitate seepage along the interface and erosion of the core-base which, in turn, could lead to a major internal erosion process. Several dam incidents and failures were initiated following this mechanism. For instance, an imperfect core-foundation treatment was one of the causes of the Teton Dam collapse in 1976. Therefore, it is clear that this surface requires specific study and treatment. Stripping, cleaning, removing unsuitable materials and shaping, are consid...
