摘　　要：瓦斯河龙洞水电站是以发电为单一开发目标的引水式电站,随着时间推移电站需经历近期到远期两种不同库水位运行条件,因此,电站设计阶段,其取水防沙措施必须兼顾拦沙、拉沙、导沙等设施的近期和远期两种运行条件,并能节省投资和方便未来施工改造,这在一定程度上增加了优化设计和模型试验的难度。通过水工模型试验研究,开展了该电站不同时期引水防沙的研究,并对枢纽导沙、防沙设施布置及结构尺寸进行了优化,从而较好解决了电站的引水防沙问题,也为以后类似的需分期运行的电站如何处理好不同时期的泥沙问题提供一定的参考。Longdong hydro-power station in Wasi River is a diversion type power station with the only development purpose of generating electricity. It is very difficult to design water intake and sediment control,which must be operated in two different water level conditions to prevent and flash sediment,and to save the investment at the same time. A physical modeling study on water intake and sediment control was conducted in this paper to optimize the layout of hydro-junction and structural format. The suggestion for water intake and sediment control is provided based on the model experiment. Finally,a operation scheme at different stages is suggested for sediment problem of the hydro-power station.
