摘　　要：超浅吃水2万吨级肥大型运煤船为我国“八五”攻关项目。作者针对该船超浅吃水的特点，根据快速性、耐波性与操纵性的要求来确定其主尺度，并设计了三种前体线型和四种后体线型，进行了多种方案组合在压载和满载状态下的阻力、自航试验及尾部伴流场测试研究，优选出适合我国港口航道的超浅吃水肥大型船舶的设计线型。实船试航结果表明，该船水动力性能优良，且阻力性能与模型试验结果吻合良好。The construction of full form coal ships with extremely shallow draft is one of the hey technique equipment projects in the 8th national five-year economical development plan.The 20000 DWT coal ship is one economical type of the ships mentioned above for the Qin huangdao-Shanghai route.The investigation on such extremely shallow draft full ship form is rarely seen both at home and adroad. On the basis of successful development of the 35000 DWT shallow draft coal ship of full form, the authors developed further a new ship form with B/T =4. 0 hav ing very good powering performance. The investigation included comparative resistance and propulsion tests with 3 different fore-bodyand 4 different aft-body lines and 3 wake survey tests at the propeller disk.The lines proposed is adopted by the owner and the shipyard. Now the ship is under construction. This investigation is also valuable for reference for the design of other shal low draft coal ships.
