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。 -
