摘　　要：富余水深的合理设置对于不同季节、不同海况的船舶安全航行具有非常重要的意义。本文建立基于水动力理论的船舶富余水深计算模型,使用Huuska方法对船舶下沉量进行计算,得到船舶富余水深的计算公式,分析不同规格船舶富余水深计算值和测量值之间存在误差的原因,提出将统计学应用到船舶富余水深计算中,基于散货船的历史经验数据建立一元回归模型。基于统计学的富余水深计算结果对水动力富余水深计算模型是一个很好的补充,实践中将两者结合将有利于提升富余水深计算准确率。The reasonable setting of surplus depth is very important for the safe navigation of ships in different seasons and sea conditions.This paper establishes a calculation model of ship's surplus water depth based on hydrodynamic theory,uses Huuska method to calculate ship's subsidence,and obtains the calculation formula of ship's surplus water depth,ana-lyzes the reasons for the errors between the calculated value and the measured value of ship's surplus water depth of differ-ent specifications,and proposes to apply statistics to the calculation of ship's surplus water depth.Based on the historical ex-perience data of bulk carriers,a single regression model is established.The results of surplus depth calculation based on stat-istics are a good supplement to the hydrodynamic surplus depth calculation model,and the combination of the two will help to improve the accuracy of surplus depth calculation in practice.
