摘　　要：连云港赣榆港区一期工程土质为5、6级黏土,绞吸船在施工该土质时受黏土黏性的影响,容易糊绞刀且输送极为困难,施工流速、浓度控制不好就会存在堵管的风险,严重影响船舶正常施工。重点对绞吸船的挖掘方式和输送理论进行研究,通过改变切泥厚度、进尺、浓度、流速等参数,解决上述问题。Affected by the level 5 ＆ 6 clay soil of Lianyungang Ganyu port area phase I project, the operation of CSD is rather difficult. Focusing on the CSD＇ s dredging methods and transportation theory, we solve relevant problems by changing the mud thickness, cut footage, concentration, as well as the flow velocity.
