Abstract:

The large-scale hydraulic lifting dam, built in Haicheng, Liaoning Province, is the largest one with water-retaining area of 960m2 and reservoir capacity of 336.79 million m3 in alpine region of China. Appropriately solving the ice prevention problem as well as flow energy dissipation in flood season are the essential keys for the project construction. By the accumulated experience in the constructing of a pilot one, we put forward the design ideas for ice prevention and flood energy dissipation for the hydraulic lifting dam, and satisfying results were obtained in practice. The design solution could be referred by other hydraulic lifting dams.

Key words: hydraulic lifting dam, ice thrust, flood energy dissipation, alpine region
