摘　　要：为适应推船与驳船间的二销联接方式,江海驳具有凹槽尾型,船组的阻力与常规船舶有较大的差异.文中在船模试验的基础上,回归出两种常用凹槽长度区间的江海驳剩余阻力计算式,提出了江海驳的阻力预报方法;得到阻力性能较优的江海驳尾型——隧道尾.采用编队系数的方法,得到船组的剩余阻力,进而预报出船组的总阻力.The stern of river/sea barge is designed to the notch form to adapt the connected requirement between pusher and barge by couple-pins. The resistance of the train is far away from the traditional ships. Based on the experiments of the ship model, the article, firstly, obuains the regression equation of the residual resistance of the barge according to the common length of the notch, gives the total resistance prediction method of the barge; secondly, finds out that the tunnel stern has minimum resistance among three stern form; finally, obtains the residual resistance of the train by means of the formation coefficient method and predicts the total drag of the train.
