【摘要】：沙灣水電站發(fā)電尾水至安谷水電站回水末端水位未銜接,致使大渡河下段未能形成貫通的渠化航道,通航條件較差。擬通過建設(shè)大渡河沫水航電樞紐,以實(shí)現(xiàn)大渡河下段航道的連續(xù)渠化,改善大渡河下段通航條件。采用整體河工模型進(jìn)行試驗(yàn)研究,分析了不同運(yùn)行工況下樞紐上下游河段的流速與流態(tài)變化情況。研究表明,依據(jù)改進(jìn)方案建設(shè)的沫水航電樞紐實(shí)現(xiàn)了大渡河下段航道的連續(xù)渠化,起到了改善通航條件的效果,但改進(jìn)方案還存在一些問題,須通過進(jìn)一步的試驗(yàn)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.
