To deal with the stability problem of revetment on the soft foundation of port engineering in coastal areas,we study the application of CFG pile in revetment reinforcement of port engineering by taking a wharf engineering in Zhuhai as an example.By theoretical analysis,we prove the applicability of CFG piles in revetment reinforcement.By the SLIDE software calculation,we know that the composite foundation treated by CFG piles satisfies the requirement on the overall stability of the revetment.In order to reduce the impact of existing revetment such as the compaction of CFG pile,some engineering measures should be taken into account in the process of construction,such as driving interlace.The post-construction pile strength verification and small-strain dynamic test reveal that CFG piles met the design requirements.In conclusion,the CFG pile treated by some engineering measures can be applied for the revetment reinforcement with a satisfactory effect and good economic benefit,thus it can be widely used for the reinforcement of high-pile wharf.
