【摘要】：沙湾水电站发电尾水至安谷水电站回水末端水位未衔接,致使大渡河下段未能形成贯通的渠化航道,通航条件较差。拟通过建设大渡河沫水航电枢纽,以实现大渡河下段航道的连续渠化,改善大渡河下段通航条件。采用整体河工模型进行试验研究,分析了不同运行工况下枢纽上下游河段的流速与流态变化情况。研究表明,依据改进方案建设的沫水航电枢纽实现了大渡河下段航道的连续渠化,起到了改善通航条件的效果,但改进方案还存在一些问题,须通过进一步的试验加以改善。
[Abstract]:The water level of the backwater end of Shawan Hydropower Station is not connected to the end of the backwater of Angu Hydropower Station, which leads to the failure of forming the channelized channel in the lower part of the Dadu River and the poor navigation conditions. In order to realize the continuous channeling of the lower section of the Dadu River, the navigation conditions of the lower section of the Dadu River will be improved through the construction of the Dadu River Moo Hydropower Hub. The variation of flow velocity and flow pattern in upstream and downstream reaches of the hub under different operating conditions were analyzed by using the integral river engineering model. The study shows that the foaming water navigation and power hub constructed according to the improved scheme realizes the continuous channelization of the channel in the lower section of the Dadu River, and has the effect of improving the navigation conditions. However, there are still some problems in the improvement scheme, which should be improved through further tests.
