摘　　要：通过分析新疆某水库溢洪道和导流兼放空洞的水力特性,验证其设计的合理性,并提出优化方案。结果显示:初设方案下宣泄洪水时,水流在消力池末端挑射、水跃未在池内形成及退水渠段流态恶劣。基于初设方案试验结果中存在的问题,对溢洪道侧槽段、泄槽段、消力池段和导流兼放空洞曲线段进行优化调整,经优化后,整体水流流态均较好,均可将水跃控制在消力池内,消力池及退水渠均不存在翻水现象,满足安全泄洪要求。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.
