New technology and innovation on flood discharge and energy dissipation of high dams in China
The waterpower construction in China has being got rapid development during the recent 60 years,especially in the 30 years after the reform and opcning up,many world-class giant water conservancy projects arc constructed or under construction.To meet the urgent need of the project construction with advanced and safe flood discharge and energy dissipation scheme,the study of high speed flow and flood discharge and energy dissipation with high head and large discharge flowrate have reached the world leading level.Several important research results on flood discharge and energy dissipation with high head and large flood discharge are introduced in the paper,which includc combined dissipater with flaring pier,slit-type bucket dissipater,inncr dissipater,air entrainment and cavitation alleviation in high head spillway tunnels,and energy dissipation in plunge pool with high head arch dam.
