摘　　要：针对广西钦州港大榄坪1号,2号泊位在施工过程中出现的滑移情况提出了5种不同的处理方案,通过技术经济分析,最后确定采用加长螺杆紧固底板法将大圆筒起浮复位。经对施工完成后位移情况的观测,表明所采取的措施是有效的,确保了整个码头的施工质量。During the construction of Berth 1 and 2 at Dalanping in Qinzhou Port of Guangxi, the large diameter cylinders slipped before backfilling. This article proposes five different methods to tackle the problem. After technical and economic com- parison, the re-position method using longer screws to secure the soleplate was adopted. Based on the observation of re-posi- tioned large diameter cylinders, it proved that adopted measures were effective to ensure the construction quality of the berths.
