摘　　要：自卸砂船是内河中常见的一种船型,由于装卸效率高、对码头及岸线适应性强、经济效益好,近年来得到了迅猛发展。但因为货舱的特殊形状致使货物重心偏高,同时散货滑移附加力矩较大,导致船舶稳性不足,翻沉事故时有发生。本文探讨通过平舱技术降低货物重心高度,减少货物滑移附加力矩影响,减少侧受风面积,进而改善稳性,提高安全系数。Self-discharging sand ship is a common type of ship in inland river. It has been developed rapidly in recent years because of its high loading and unloading efficiency, strong adaptability to wharf and shoreline, and good economic benefits. However, due to the special shape of cargo hold, the cargo center of gravity is on the high side, and the additional moments of bulk cargo slip are large, which leads to the insufficient stability of the ship and the accidents of overturning and sinking occur from time to time. This paper discusses how to reduce the height of cargo center of gravity, reduce the influence of additional moment of cargo slip, reduce the area of side wind, and improve stability and safety through flat cabin technology.
