摘　　要：为了解决在菲律宾帕赛市-SM集团吹填开发项目(I期)中存在的回填作业区软土层含水率高、强度低,平均厚度大,直接吹填施工时,地基极易出现挤淤及局部失稳,影响后续施工质量的问题,提出了深厚软土层上的“三合一”船进退法分层回填关键工艺,工艺从进退法施工、方量测量作业、施工船组调度等方面进行优化。深厚软土层上的“三合一”船进退法分层回填关键工艺有着较高的施工效率,有效解决了深厚软土层上的回填施工质量控制问题,可为深水条件下的大型填海项目提供参考和借鉴。In order to solve the problems of high water content,low strength and large average thickness of the soft soil layer in the backflling operation area in the reclamation development project(Phase I)of the SM Group in Pasai City,Philippines,when direct reclamation is carried out,the foundation is prone to silt squeezing and local instability,which affects the quality of subsequent construction,the key technology of layered backfilling by the"self-priming and self-unloading"ship advance and retreat method on deep soft soil layer is proposed,and the technology is optimized from the aspects of advance and retreat construction,volume measurement,construction fleet scheduling,etc.The key technology of layered backfilling by the"selfpriming and self-unloading"ship advance and retreat method under the backfilling on deep soft soil layers has high construction efficiency,effectively solving the quality control problem of backflling construction on deep soft soil layers,and can provide reference and inspiration for large-scale reclamation projects under deep water conditions.
