Abstract
Shankou Hydropower Project, with the total storage capacity of 2.22 million m3 , Grade 2B in scale, is located in the extremely cold and dry region, Xinjiang Autonomous Region.The water-retaining structure is the conventional concrete double-curvature dam with maximum height of 94 m.The dam concrete totally applies the fully graded aggregates.At the feasibility study stage, the key technical is-sues such as overflow cofferdam for river diversion, fully graded-aggregate concrete, dam concrete placement means and temperature con-trol, etc are studied in the construction method statement in combination with local climate, river diversion, flood control, four graded ag-gregates, landform conditions, etc.关键词
