In order to solve the problems of high water content,low strength and large average thickness of the soft soil layer in the backfilling 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"self-priming 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 backfilling construction on deep soft soil layers,and can provide reference and inspiration for large-scale reclamation projects under deep water conditions.
