Because of the "middle obstruction" of the Yangtze River, the construction of artificial waterways in the middle reaches of the Yangtze River has been put on the agenda. At present, the Yangtze River ships are in a large-scale development trend. For 10,000-ton ships, the Yangtze River artificial waterway is restricted water with small section coefficients. In this paper, the low-speed full and 10,000-ton ship is taken as the research object. Select the ship resistance and the vertical suction force of ship during navigation as the research indexes. The experiment simulates the inclined bank channel with a slope ratio of 1:3, subsequently, by varying ship speeds, ship-to-shore distances and channel water depths, analyzing the impact of channel and ship speed on 10,000-ton ships. Using CFD to calculate the model experiment conditions, the CFD calculation results are in good agreement with the model experiment results, and change the scale ratio to obtain the ship resistance and ship vertical suction force of different scale-ratio models by CFD. Obtain the influence law of the scale ratio on the ship's resistance and the vertical suction force of the ship, which has guiding significance for navigation performance of ships in restricted waters and the large-scale development of ships in the restricted waters in the future.
