摘　　要：采用遥控自航船模和牵引船模相结合的方法,对船队进出船厢的水力特性进行了试验。成果表明:船队进出厢的航行阻力和下沉量取决于船厢断面系数和进出厢的速度。断面系数减小,航速增加,阻力和下沉量增大;出厢的阻力和艉沉均大于进厢;结合国内的部分研究成果以及国内外的工程实践,初步提出了承船厢尺度的确定原则。The hydraulic characteristics of ships passing through the chamber is studied with self propelled ship and towing ship model tests. It is shown that the ship sailing resistance and ship sinkage are dependent on cross - section coefficient of the chamber and sailing speed. Sailing resistance and ship sinkage will augment if the cross - section coefficient is diminished and sailing speed is increased. The sailing resistance and sinkage of ships sailing out of the chanber are larger than that of ships sailing in. Based on some study results and practical works both at home and abroad, the principle to difinite the dimension of the ship carrying chamber are proposed.
