摘　　要：双销式江海直达顶推船组(队)的减阻问题是一个值得探讨的研究课题.为满足船组(队)的耐波性能,与推船联结的江海驳尾部通常设计成凹槽尾形,导致在联结区域产生较大的形状阻力.文中针对(1)江海驳尾部凹槽的长度区间;(2)推、驳联结区域的线型设计;(3)江海驳尾部凹槽的选形与加装导流板等方面开展船组(队)的减阻设计与试验研究.The study of reducing resistance for river/sea pusher barge combination/fleet is one of the focus technologies limited by the connection mode which is connected by two pins between pusher and barge. The stern of the river/sea barge is usually designed with a notch to make more shaped （vortex） resistance. Three aspects have been discussed to reduce the residuary resistance of the combination/fleet as following： （1） the length span for the notch design of the river/sea barge; （2） the key points about the design of aft-bodyline in the connection location;（3） the optimum design about the stern shape of the river/sea barge and the improved effectiveness of adding a eddying plate located in the bottom of the notch. Some results have been obtained by ship model tests.
