摘　　要：大直径PHC管桩在海上应用较少,针对海上潮汐海水流动等影响定位和成桩施工过程中出现的问题,通过对福州港沙埕港区某作业区项目的大直径PHC管桩施工,提出大直径PHC管桩施工海上施工关键技术,解决了相应施工难题。Large-diameter PHC pipe piles are seldom used in the offshore area,for the influence of tidal and seawater flow in the sea,the positioning and piling construction have been carried out.According to the problems in the process,the large diameter PHC pipe pile construction of a project in an operation area of Fuzhou port is put forward.The key technology of offshore construction of diameter PHC pipe pile solves the corresponding construction problems.

关 键 词：大直径 PHC管桩 海上 定位
