摘　　要：某炼油项目部分场地为海域吹填砂,根据场地表层和上部地基稳定性较差、中下段地基整体稳定性较好的特点,采用预制方桩基础。介绍该工程沉桩、接桩、送桩工艺和对桩头破碎、挤土效应导致邻桩破坏等现象的处理方法。Some parts of a refinery project are located on costal backfilled sand foundation, where the surface and upper part have poor stability and the lower part has relatively good stability, so precast square pile is adopted. Introduction is made on pile sinking, pile splicing and pile follower processes, as well as treatment methods for pile head breakage, neighbor pile damage caused by squeezing effect, etc
