The Test research for Energy Dissipation structure of Y-flaring pier stilling basin in Saige Hydropower Station

Dong Bao-shun,Liu Shan-jun  
For the characteristics of the low water head,large discharge per unit,low Froude Saige Hydropower Station posses,and the energy dissipation of discharge flood stands out.Based on hydraulic model tests,the energy dissipation structure of Y-flaring pier stilling basins is put forward.After them were employed,the flow jetted is stretched,which increases the area of the interface between the water flow and air,the shrinking flow passing the piers to jet into the stilling basin which has 3D short flow characteristics,and has resolved the second flow fall down and the erosions and energy dissipation in downstream channel.
