摘　　要：天津地区某疏浚工程采用大型绞吸船施工,最远吹距达17 km。针对单艘非自航大型绞吸挖泥船无法满足工程长吹距施工的问题,研究大型绞吸船串联施工技术。通过去除自有闲置绞吸船桥架、钢桩定位等系统,并增设锚缆定位等辅助设备的方式,针对串联施工对大型绞吸船进行适应性改造;通过对串联施工多种工况的理论计算,确定两船的最佳施工间距范围,提升大型绞吸船串联系统的生产率和稳定性,保障工程按期完成。结果表明:大型绞吸船串联施工设备改造方案及施工工艺满足工程长吹距施工要求,降低生产成本,减少船舶停滞,提升生产率约24%,效果显著。A dredging project in Tianjin is implemented with a large cutter suction dredger,and the maximum discharge distance of the project is about 17 km.Since a single non-self-propelled large cutter suction dredger cannot meet the requirement of long discharge distance construction,the series connection construction technology of large cutter suction dredgers is studied.By removing the bridge frame,steel pile positioning,and other systems of idle cutter suction dredgers and adding auxiliary equipment such as anchor cable positioning,the adaptive transformation for the large cutter suction dredgers is carried out through series connection construction.Through the theoretical calculation of various working conditions of series connection construction,the optimal construction spacing range of two dredgers is determined.The productivity and stability of the series system of the large cutter suction dredgers are improved to ensure the completion of the project on schedule.The results show that the equipment reconstruction plan and series connection construction technology of large cutter suction dredgers can meet the project requirements of long discharge distance construction,reduce production costs and idle dredgers,and increase productivity by about 24%,with remarkable results.
