摘要
介绍了内河船舶上滩阻力的计算方法,利用概化急流滩模型的船模上滩的试验资料,对比分析各阻力计算方法表明,本文提出的修正的兹万科夫法能较好地计算受浅水和狭水道影响的船舶阻力,并可用于滩口下游水面为倒比降滩段的船舶阻力计算.
Calculation methods for resistance of ships ascending rapids are presented, and the calculation methods are compared and analyzed by using the experimental data of ships ascending rapids in a generalized rapids model. Results show that the modified Эиванков method presented in this paper can reflect the influences of the shallow and narrow channel, and can be used to calculate the ship resistance in the downstream rapids of the beach mouth with an inverse slope.
