摘　　要：超大型自航绞吸挖泥船不仅具备海底岩土超强挖掘和长距离高效输送的作业能力,还具有高海况适应和高度自治能力,已成为港口、人工岛和吹填造陆等重大基础设施建设不可替代的装备,为大型疏浚公司发展的首选船型。该文分析了国际上超大型自航绞吸挖泥船的发展态势,回顾了我国大型绞吸挖泥船的发展历程。简述了绞吸挖泥船的工作原理和系统组成,从疏浚土质、产量、挖深、排距和环境条件等方面分析了绞吸挖泥船设计应重点考虑的因素。全面分析了“昊海龙”设计方案中的船型与总布置、绞刀驱动、桥架结构设计、泥砂输送、柔性钢桩、全电力驱动和居住舱室减振等关键技术,其采用的绞刀双电机长轴驱动、双壳箱型桥架结构、泥泵三泵组合、柔性钢桩和全电力驱动等技术对超大型绞吸挖泥船是非常适宜的。文中提出的绞吸挖泥船设计原理和对“昊海龙”设计技术的介绍,可为超大型自航绞吸挖泥船开发提供参考。The ultra-large self-propelled cutter suction dredger not only has the operating capacity of the ultrastrong excavation and the long-distance efficient transportation of the seabed rock,but also has the adaptability to high sea state and the ability of high autonomy.It has become the irreplaceable equipment for major infrastructure constructions,such as port,artificial island and land reclamation,which is the preferred ship type to be developed for large dredging companies.This paper analyzes the development of the international ultra-large self-propelled cutter suction dredger,and reviews the development history of the large cutter suction dredger in China.The operating principle and system composition of the cutter suction dredger are briefly described to analyze the key factors to be considered in the design of the cutter dredger regarding the dredging soil quality,capacity,digging depth,discharge distance and environmental conditions.It comprehensively analyzes the key technologies of the design scheme of the“HAO HAI LONG”,such as the ship type and general arrangement,the cutter drive,the structure design of the bridge,the mud and sand transportation,the flexible steel pile,the full electric drive and the vibration reduction of the accommodation.The technologies of the long-shaft drive with double motor for cutters,the double shell box type bridge structure,the combination of three dredging pumps,the flexible steel pile and the full electric drive are very suitable for the ultra large cutter suction dredger.The design principle of the cutter suction dredger and the design technology of the“HAO HAI LONG”can provide references for the development of the ultra large self-propelled cutter suction dredger.
