摘　　要：开体泥驳是辅助大型挖泥船疏浚施工关键设施之一。针对国内研发的4 000 m3大型自航艏吹开体泥驳,分析泥驳通过左右两个半体开启快速卸泥、在浅水区域卸泥、通过溢流筒装置实现不同装舱高度溢流、通过艏吹装置进行吹岸作业等功能特点,提出此类型船设计的关键技术,解决了船舶开体状态稳性、液压缸及泥舱密封等一系列技术难题,掌握了大型自航艏吹开体泥驳核心技术,为同类型船的设计提供借鉴。The split hopper barge is one of the key facilities that assists large dredger dredging construction.In view of the domestic research for the 4 000 m 3 large-scale self-propelled bow-connection split hopper barge,this paper analyzes the functional characteristics of the barge,i.e.opening the left and right half bodies for quick mud unloading,being capable of unloading mud in shallow water area,realizing overflow of different cabin loading heights through an overflow units,carrying out the shore blowing operation by the bow blowing device,etc.,the paper proposes the key technology of this type of ship design,and solves a series of technical problems such as the ship’s splitting status stability,splitting hydraulic cylinder,as well as mud tank sealing,etc.,and grasps the core technology of the large self-propelled bow-connection split hopper barge,so as to provide reference for the design of the same kind of ship.
