摘　　要：针对龙溪口航电枢纽工程施工明渠临时通航问题,基于数学模型及实船试验,研究施工明渠局部疏浚淤积后船舶临时通航的水流条件及船舶试航情况。数学模型模拟了施工明渠局部清淤形成的临时航道的水深及流速,均满足船舶安全航行要求。不同吨级船舶装载及空载条件下,试验的实船可安全上下行通过龙溪口施工明渠临时航道,为枢纽建设过程临时航道通航范围及尺度的确定提供依据。This paper probes into the temporary navigation in the open channel for the construction of the Longxikou navigation power junction. Utilizing a mathematical model and a real ship test, it studies the flow conditions for temporary navigation and trial navigation results after the local dredging of the open channel. The mathematical model simulates the water depth and flow velocity of the temporary channel formed by the local dredging of the open channel for construction, both of which meet the requirements of ships for safe navigation. Under the loading and no-load conditions of vessels with different tonnages, the real ships in the test can safely go up and down through the temporary channel of the open channel for the construction of the Longxikou navigation power junction, which provides a basis for determining the navigation scope and scale of the temporary channel during the construction of the junction.
