該方法具有很強的指導意義和推廣價值，可為蘇北運河船閘設計、管理和發展提供科學依據，同時也可為國內其它河流上的船閘設計、以及《船閘總體設計規范》的修訂提供參考。To provide necessary data for design bypass pipe, an enlargement to bi liu river reservoir, the following problems have been studied by hydraulic model and theoretical analysis : the energy losses in water head of the bypass pipe system and of the flow - control valve and their scale effects, measurement and calculation of the discharge of the bypass pipe system during the bypass pipe system operation with and without the new water power station, the hydraulic characteristics of the water tunnel and draw - off pipe, the flow rate of the aqueduct bridge and the draw - off pipe and the water elevation of the flow in the aqueduct bridge during the old water power station operation with and without the new water power station
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。Finally, the renovate of dong gou lock improve navigation circumstance of vessels and it will minimize ship ' s collision and cargo damage accident and it also has advantage of low cost, low pollution, environment friendly, good view of nearby circumstance and so on. shen wei ( communication transportation ) directed by. answering date : mar 28th 2002
第三、東溝船閘改造改善了船舶運行條件，將減少過閘船舶的船損和貨損事故；將有利於充分發揮內河運輸運運量大，成本低，污染小的優勢；並能興水利、除水害、防止岸坡坍塌和水土流失，保護耕地，綠化環境，美化景觀，具有良好的社會效益。In order to solve the turaoff facing yellow river now, we need supervise the flux by the long - distance measurement
為了更好地解決黃河下遊河道斷流的問題，有必要對引黃涵閘過流量進行遠程監測。The result show that the position of free surface is higher because of frusta of brake, especial obvious in the head of frusta of brake ; flux coefficient and pressure on dam are quite influenced by type of frusta and 3 a type frusta of brake relative to 2 type frusta of brake has bigger flux coefficient and smaller pressure on dam ; obvious influence of ability of discharge flow for different ratio of thickness of frusta and breadth of brake and pressure on dam reduces with increasing ration of thickness of frusta and breadth of brake, while bigger flux coefficient is obtained when tlb = 0. 2
結果表明，閘墩河海大學博士論文的存在抬高了水面線的位置，其中在閘墩頭部尤其明顯;墩型對流量系數和壩面壓力影響較大， 3a型閘墩相對於2型閘墩具有更大的流量系數和更小的壩面壓力:不同的墩厚閘寬比t / b對泄流能力也將產生顯著的影響，隨著墩厚閘寬比的增加，壩面壓力降低，而當t / b二0 . 2時溢流壩具有更大的流量系數。The results showed that the water quality pollution of the whole basin is not serious and can achieve the water quality standard of this region basically
結果表明：流域水質具有明顯的區域差異，在14個典型監測斷面中，福山水閘下和新夾河橋2個監測斷面水質污染較為嚴重，宮家島等4個斷面水質較好，其餘斷面水質良好。In case a non - navigable stream or man - made waterway becomes navigable after a dam or sluice gate structure is built, the construction unit shall simultaneously build ship passage facilities or reserve sites for such facilities, and the expenses needed thereby incurred shall be borne by the communication departments concerned, unless there are other state - provisions applicable
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。This paper studies the influence of different riverside shape on the flow condition of low - head hydraulic lock ' s outlet area through mathematical computation and examples of project, and finds out the riverside shape which is the most advantageous one
摘要通過概化模型計算並結合工程實例分析，研究了凹形和凸形河岸對低水頭樞紐船閘口門區水流條件的影響，指出了對低水頭樞紐船閘口門區通航水流條件相對有利的河岸形態。Abstract : the outflow through gate controlled multi - opening spillway of yinhe reservoir was analyzed. the analysis results were checked by the site observed data
