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
