摘　　要：在港池航道疏浚工程中,由于受到港区水域水流泥沙输移的影响,常常发生施工期回淤现象。随着浚深不断增加,平均淤积强度逐渐增大,给工程项目的进度和质量管理带来了巨大挑战。本文以深圳港大铲湾码头港池疏浚清淤工程遇到严重回淤问题为研究基础,通过对泥沙淤积规律的深入分析,有针对性地优化了耙吸船施工工艺,调整了船舶施工参数等措施,明显提高了耙吸船在疏浚清淤项目中的效率。In the dredging of harbor basin and channel,the sediment transport by water flow in the waters around the harbor often causes the phenomenon of siltation during the construction period.The average siltation intensity gradually increases with the increment of dredging depth,which is a greatly challenge to the progress and quality management of projects.Based on the difficulty in backfilling in the dredging and desilting of harbor basin at Dachan Bay Terminal in Shenzhen Port,an in-depth analysis was carried out for the sedimentation law,which led to the optimum construction process of trailing dredger,modified vessel parameters for the dredger and etc.The above measures significantly improved the efficiency of the dredger in similar projects.
