摘　　要：川江及三峡库区航道水深季节性变化大,为了充分利用水深条件,船舶多采用变吃水设计,船舶航行时载况的变化会引起主机、螺旋桨的工况发生变化,因而船舶营运经济性的计算有别于常规船舶,对船舶营运经济计算中载货量、航速及经济参数进行分析,实例计算结果令人满意。Since the depth of water way changes with the season, bulk carriers in Changjiang river within Sichuan province and waterway in Three-Gorge reservoir usually adopts the changeable-draft technique. The difference of draft causes the change of the speed as well as the working condition of main engine and propeller, so when the transport economy is calculated, speed, oil cost and quantity of cargo loaded must be paid a lot of attention. This paper analyzes the method of transport economy and applies this way in research work.
