摘　　要：本文以浙江省沿海某围涂工程为例,描述了龙口段合拢施工过程中如何通过对拉船施工工艺的灵活运用,成功解决了本项目西堤龙口狭小浅水区域内铺设软体排的难题,与传统工艺相比,避免了项目范围内水深不满足船舶施工作业区域的开挖环节,减少了设备和人力的投入,缩短了工期,节约了施工成本,取得了较为理想的实施效果。本项目采用的新型对拉船组定位方式也为今后软体排的铺设工艺提出了一种新的借鉴方案。An introduction to a sea reclamation project in Zhejiang province includes the flexible use of towed ships to successfully solve the difficulty of laying mattress in a narrow shoal located at the closure-gap of the project’s west embankment during the closure-gap construction.Compared with the traditional technology,the new one avoids the dredging works caused by the limited water depth that does not meet the ship’s operation requirements,reduces the investment of equipment and manpower,shortens the construction period,lowers construction cost,and achieves an ideal effect.The new positioning method of towed ships will also provide a reference for laying mattress in the future.
