摘　　要：为解决承台钢板桩围堰施工技术在具体应用中存在的问题,结合横跨伶仃洋的拱北湾大桥工程实际案例,对跨海大桥承台钢板桩围堰施工进行了分析,提出采用承台钢板桩围堰施工可有效缩短工期,满足预期的施工质量要求。由于跨海大桥的地质环境复杂,采用基于钢板桩围堰技术的承台施工,同时严格制定桥梁承台钢板桩围堰施工安排,确保施工质量和安全保障,能够满足施工需求,值得同类工程借鉴参考。In order to solve the problems existing in the application of bearing platform steel sheet pile cofferdam construction technology,this paper analyzes the cofferdam construction technology of the sheet pile of the bearing platform of the cross-sea bridge project on the basis of the actual case of the Gongbei Bay Bridge project across the Lingdingyang.It is proposed that the use of bearing platform steel sheet pile cofferdam construction effectively shorten the construction period and meet the expected construction quality requirements.Due to the complicate geological environment of the cross-sea bridge,the construction arrangement of steel sheet pile cofferdam for bridge bearing platform should be strictly formulated to ensure the construction quality and safety guarantee.The cofferdam construction technology of the sheet pile of the bearing platform can meet the construction requirements and provide reference for similar projects.
