By analyzing the structure and transportation mode of sinking tube segments, combined with the theoretical analysis of fluid mechanics, we establish aresistance calculation model, and choose the appropriate floating transportation plan according to the actual situation. The results show that the floating resistance of large sinking tube segments is affected by multiple factors, including the length, diameter, fluid velocity, and fluid density of the tube segment. At the same time, the choice of floating transportation plan also has an important impact on resistance. Reasonable floating transportation plan can reduce resistance and improve transportation efficiency. This paper provides specific methods for resistance calculation and floating transportation plan, which can provide reference for similar research.
