Projects Description
Palik is a zoned embankment dam with impervious core.
Its typical section presents different zones, from upstream to downstream: an upstream shell (rockfill), a transition zone (sandy-gravelly material), a core (clayey material), two filters (sandy and gravelly materials) and a downstream shell (same as upstream shell).
For surface foundation preparation a stripping of 1-1.5 m is foreseen. The core was deepened up to the top of the bedrock, that lies 6-10 m below the ground level; this solution was considered the most effective and simple to get the tightness of the foundation. As for typology, a homogeneous cofferdam was preferred; excluding an impervious homogeneous embankment (no suitable natural material is available), a rockfill embankment with an upstream impervious device was chosen.
