Observation Study on Water Discharge Structure for Dongping Hydro Junction
In this paper the technical method and relevant research results for observing hydrodynamic pressure of stilling pond bottom is introduced when the dam is respectively discharging by middle and surface outlet. The research result indicates that in the observation of working condition the water tongue is fully aerated. After it drops to the stilling pond, the energy cut back fast. The table of discharge due to upstream water-hole high-flow large. As a result of high water level at upstream and large flow, the fluctuating pressure of surface outlets is larger than middle outlets. But the measurement shows that the amplitude fluctuating pressure in the plunge pool is small and the energy is low. Besides the parameter values are within the allowable range in the design. It can be concluded that the water discharge structure discharges smoothly and the stilling pond operates safety.
