Abstract
By analyzing the hydraulic characteristics of the spillway and the combined guide and drawdown tunnel of a reservoir in Xinjiang,this study verifies the rationality of their design and proposes optimization solutions.The results show that under the initial design scheme,when discharging floodwater,the flow jetted out at the end of the energy dissipation basin,hydraulic jumps did not form within the basin,and the flow conditions in the outlet channel were poor.Based on the issues identified from the initial design scheme test results,optimizations were made to the side channel section,chute section,energy dissipation basin section,and curved section of the combined guide and drawdown tunnel.After optimization,the overall flow conditions improved significantly,with hydraulic jumps controlled within the energy dissipation basin,and no water overturning observed in the energy dissipation basin or outlet channel,thus meeting the requirements for safe flood discharge.关键词
