    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。
  2. By the analysis and study, it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently

    然後以實測資料為基礎分析研究了三門峽建庫前後潼關高程的變化規律以及渭河下遊河道的沖淤演變規律,分析研究表明:建庫前渭河下游主槽處于動態沖淤平衡狀態,灘地處于微淤狀態;建庫后,渭河下遊河道發生嚴重淤積主要是由於潼關高程的抬升造成的;潼關高程的抬升主要是由於三門峽水庫的不合理運用造成的,近期不利的水沙條件加劇了潼關河床的抬升速度和渭河下游的淤積。
  3.
