- Abstract
In order to ensure the best energy dissipation effect of energy dissipation wells in water release tower under the condition of structural safety, the influence of different sizes of energy dissipation wells to the floor pressure, floor fluctuation characteristics and other hydraulic parameters was studied by model test. Taking the diameter D0 of the outlet tower as the measurement criterion, changing the well depth H0 or diameter D is studied under the conditions of H0=0.5×D0,H0=0.77×D0,H0=1×D0,H0=1.5×D0 and D=1×D0,D=1.33×D0,D=1.67×D0. The results show that the larger the depth and diameter of energy dissipation wells, the smaller and more uniform the time-average pressure on the floor, the lower the peak frequency of fluctuating pressure, the better the structural stability and energy dissipation effect. Considering structural safety and construction cost, the size of energy dissipation wells is optimized. The reasonable size of energy dissipation wells is H0/D0=0.77,D/D0=1.00 or H0/D0=0.50,D/D0=1.33.
