本文由内河分节顶推船队的综合经济指标E,推导出内河分节顶推船队的推船功率与驳船队最佳匹配关系式,进而讨论了成本结构的主要因素的变化对分节顶推船队规模及经济性的影响,并通过对长江下游分节顶推船队的技术经济论证,指出长江下游近期内发展大型船队和大功率推船是不经济的;合理的分节顶推船队应该采用2000吨驳型、1200～1800马力推船所组成的2 x 4船队以及2000驳型和540～1200马力推船所组成的2×2船队。
In this paper, the inland section subsection pushed the fleet’s comprehensive economic indicators E, deduced that the inland section subsection pushed the ship’s power and barge team the best matching relationship, and then discussed the cost structure of the main factors of changes in section Push the scale and economic impact of the fleet and through the technical and economic demonstration of the thrust of the fleet in the lower reaches of the Yangtze River, pointed out that the development of large-scale fleets and high-power push vessels in the lower reaches of the Yangtze River in the near future is uneconomical; a reasonable sub-section The jacking fleet should use a 2 x 4 fleet of 2,000 tonne barges, 1,200 to 1,800 horsepower, and a 2 x 2 fleet of 2,000 barges and 540-1200 hp.
