摘　　要：考虑到采用兹万科夫法计算山区河流船舶阻力的局限性,结合澜沧江500 t级机动船实船静水航速试验,分析船舶阻力试验结果与兹万科夫法计算结果的偏差,提出按总阻力系数、剩余阻力、剩余阻力指数进行修正的思路和方法,建立相应修正系数与船舶弗劳德数、船宽吃水比的函数关系,对比上滩航行与静水航速实船试验结果,进行二次修正,总结出总阻力和剩余阻力二次修正系数以及适用范围。Considering the limitation of using theЭиванковmethod to calculate ship resistance in mountain rivers,the deviation between the ship resistance test results and the calculation results of theЭиванковmethod was analyzed based on the static water speed test of 500 t-class motor ship in Lancang river.The correction ideas and methods were put forward according to the total resistance coefficient,residual resistance and residual resistance index.The function expressions of the corresponding correction coefficients,Froude number and the width-draft ratio of the ship were established.The secondary correction coefficients of the total resistance and residual resistance and the applicable scope were summarized by comparing the speed test results of beach sailing with those of still water.
