The special cushion of the concrete face rockfill dam in Altas Hydro Project was mainly between the dam body and surrounding mountains whose compaction construction had the following characteristics: (1)the small and irregular construction site, (2)the very strict requirement of construction technology. Therefore there were series of in-situ tests to verify the designed rationality of compaction standard of special cushion materials, then the compaction construction technology and related construction parameters was advised, at last, the permeability property of special cushion materials and its compaction construction after sprinkling and soaking was discussed.
