Using a vortex - flow drop shaft to convey water from a high level to a diversion runnel under the condition of high water - head and large discharge is a new kind of technology in the scheme of reusing a diversion tunnel as a discharge tunnel
近年來，為解決高水頭、大流量導流洞改建泄洪洞的技術難題，旋流式豎井泄洪洞逐漸成為研究熱點之一。但迄今為止，該技術尚未得到推廣應用，其主要原因在於人們對豎井螺旋水流運動特徵缺乏足夠的了解和深入的研究。 -
The horizontal swirling flow internal dissipater tunnel being built in gongboxia power station will be the first one reconstructed from a diversion tunnel whose discharge reaches to 1000m vs and water head is more than 100m in china. its scheme ' s argumentation, test research and future apply will have important meanings to the design. research and engineering application of internal dissipation discharge tunnel with swirling flow, will powerfully promote engineering application of this new kind of dissipation mode, which may solve some high velocity problems in high dam construction and provide a engineering example for technological and economical augmentation in a diversion tunnel reconstruction. it is of theoretical and practical importance to promote hydraulic structure researches and development
公伯峽水電站右岸旋流內消能泄洪洞是國內第一個泄量達1000m s 、水頭超過100m ，即將修建的旋流式內消能泄洪洞，其方案的論證與試驗研究以及建成后投入使用，將在國內外旋流式內消能泄洪洞設計、研究與工程應用中具有重要的意義，將有力的推動這一新的消能形式在工程中的應用，從而為解決高壩建設中泄水建築物的高速水流問題與導流洞改建的技術與經濟問題提供工程實例，對推動與發展水工水力學的研究與發展均具有重要的理論與實踐意義。 -
Abstract : for high arch dams in valleys with the characteristics of high water head, large discharge and large power, the problems of energy dissipation and scour prevention are serious. based on scientific studies, new comprehensive measures are proposed, including dispersion of discharge to waken wallop of the current, and reinforcement of riverbed to enhance the erosion - resistance. the measures can be used to solve the problem of energy dissipation properly. a typical layout scheme has been proposed in which slotted bucket with diversion teeth, double deck with pores, and cushion pool are considered practice has proved that the scheme is reliable and the effect of energy dissipation is obvious
文摘:高拱壩泄洪消能的特點是壩高落差大，流量大，功率大，位於河谷狹窄地區，泄洪消能與防沖問題突出.經科學研究，採用「分散泄洪，削弱水流沖擊力，加固河床，增強河道抗沖能力」的綜合治理措施，較好地解決泄洪消能布置問題.提出了表孔大差動坎加分流齒、雙層多孔、水流撞擊、下設水墊塘聯合消能的典型布置方案，經實踐證明，方案可靠，消能效果好 -
