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。Shipment traffic usually is heavy in littoral area, the navigation capability is required in many riverway. navigation lock was set to suit for the water level ' s variety caused by tide. for a long period, being lack of the quantified assessment on the influence of saltwater intrusion, approaches that freshwater is inpoured to the lock chamber are adopted lest the high concentration salt water be imported to the inland waterway, when the navigation lock is in operation. but such manner should not be reasonale enough
沿海地區船運發達,很多河道有通航要求,為克服潮汐造成的水位變化而設置船閘。長期以來,由於缺乏對鹽水入侵內河河道產生影響的定量評估,在船閘運行過程中為防止高鹽度鹹水入侵內河,通常採用將內河淡水打入閘室的方式來調節通航水位,船閘的這種運行方式不盡合理。The positive is that as a substitute of old channel or a part of the new channel shiplock maintains the continuation of channel and makes possible the channel free from navigational obstruction and waterway transportation progress. the negative is that shiplock at the same time brings some problems to waterway transportation, such as the long time passing through shiplock, the piling up of vessels, making less other ' s benefits and making more other ' s costs, making conditions and forms of transportation change, making more complicated the waterway transportation safety management and navigation order keeping, and adding up transportation costs
在經濟學意義上,船閘具有正負外部性,正的外部性為,船閘作為原航道的替代物或新航道的一部分,保證了航道的連續性,為保證航道暢通、航運發展提供了可能;負的外部性為,船閘同時給航運帶來了一些問題,如船舶過閘時間長、船舶積壓,引起他人效用的減少和成本增加,以及運輸組織條件、方式改變,使水上交通安全管理和船舶航行秩序維護更加復雜,增加運輸成本。All kinds of resisting moment effects upon pump start - up process are fully considered and the different operational results of outlet gate with little flap valve are also reviewed

在不通航的河流或者人工水道上修建閘壩后可以通航的,閘壩建設單位應當同時修建過船設施或者預留過船設施位置,所需費用除國家另有規定外,由交通部門負擔。The pattern of flow of lower lock approach is usually complicated due to the influences of the interaction of flow underpoured from different locks. generally, physical model is applied to study the current field for the case of irregular boundaries and complex flow pattern
由於受多線船閘下泄水流相互作用的影響,船閘下游引航道非恆定流流態十分復雜,對於此類有復雜流態的非恆定水流運動問題一般採用物理模型進行研究。Shankou spillway project has many specific characteristics, for example, the gate frusta and weir body have equivalent thickness, the weir body is low and have corridor, the foundation of the weir body is " high - low foot " " and the side frusta is also used as retain wall. in view of the characteristics, to better analyze the stress distribution on weir body, gate frusta, the joints between gate chamber and weir body, under the condition that the gate chamber is applied with asymmetrical loads and complicated constraints, three dimensional finite element method is applied in this paper
