摘　　要：以典型抽水蓄能电站为研究对象,开展了水库防沙措施研究。针对复杂工程条件,在分析各种防沙布置措施的基础上,考虑以沉代拦、导沉结合,提出导沙堤和尾水明渠相结合的防沙布置型式。经过数值模拟和物理模型验证,该型式减少过机泥沙效果明显,水力学参数合理。研究成果可为类似工程规划、设计和运行提供参考。A study was conducted on sediment control measures for reservoirs,focusing on typical pumped storage power stations.Based on the analysis of various sediment control measures for complex engineering conditions,considering the replacement of interception with sedimentation,and combination of diversion and sedimentation,a sediment control layout form combining a diversion embankments and a tailwater channel is proposed.After numerical simulation and physical model verification,this type has a significant effect on reducing sediment passing through the machine,and the hydraulic parameters are reasonable.The research results can provide reference for similar engineering planning,design,and operation.
