摘　　要：大连中远30万t浮船坞工程是目前国内最大的浮船坞工程，共设计海上基桩30根，桩径800mm，嵌入中风化岩石4～5m，最深达8m。利用驳船进行海上基桩施工，采用FGC-15D型大直径湿式反循环潜孔锤钻进成孔，满足施工工艺和工期要求。Dalian COSCO 300000 DWT floating dock is the largest floating dock engineering in China at present, with 30 sea piles of 800 mm in diameter, embedded 4 ～5m （the deepest is up to 8 m） in intermediary weathering rock. Barge was used in sea pile construction, and FGC - 15D large diameter wet reverse circulation DTH was adopted for hole completion.
