摘要
简要分析了影响内河船舶下沉量的主要因素,介绍了国内外关于船舶下沉量的研究概况及相关近似计算公式。根据Ⅲ级航道船舶下沉量测试物理模型试验结果,提出了适合内河限制性Ⅲ级航道的船舶下沉量近似计算公式。计算结果与模型试验结果对比表明,该公式达到了较高的计算精度,对航道水深计算及航道断面设计具有重要的参考价值。
Major factors causing the subsidence of inland water ships are analyzed. The researches on the problem and the calculation formulas are briefed. The calculation formula of subsidence of ships in class III restricted channel is developed based on physical model tests. The formula has high accuracy, therefore, can be a guidance to decide the depth and width of a channel.
