    大連市碧流河水庫供水工程取水頭部由引水渡槽、節制閘、進水閘、泄水閘等建築物組成。由於本工程場地條件限制,增設旁通管后布置非常緊湊,管道急轉角度大且轉彎距離較小,對于管內水流流態是否滿足要求,需要經過模型試驗進行論證,以確保工程的可靠性。旁通管具有上水與泄水要求,對其過流能力也要經試驗確定,為碧流河水庫增建旁通管設計提供依據。
  3. 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。
  4. For example, when the design flow of upward of the peace bridge of upward of the east - one main canal is 45m3 / s, the actual flow quantity is 23. 8m3 / s on the 30th of september in 1989, the water level of the transition region terminal of the mouth of hao wan flume of the east - one main canal had gained the design level of 4. 3m, and the level between downstream and shang tian yuan tunnel was generally higher. it says that the actual discharge capacity now is only about 24m3 / s which is half of the design value. this not only make the benefit of the irrigation district abnormal, but also greatly hinder the economic development of the irrigation district, and lead to the canal run frequently at small flow, high water level, lengthen the discharge duration

    如東一乾渠上段太平橋以上設計流量45m ~ 3 s , 1989年9月30日實測通水流量23 . 8m ~ 3 s時,東一乾渠郝灣渡槽出口漸變段末端水位已達到設計水位4 . 3m ,其下游至上天院隧洞水位也普遍偏高,即東一乾渠上段目前僅能通過流量24m ~ 3 s左右,只有設計值的50左右,不僅使灌區效益得不到正常發揮,嚴重阻礙了灌區范圍內的經濟發展,而且使渠道經常處于小流量、高水位運行,延長了次通水時間,大大增加了渠道工程的安全管理難度。
