摘　　要：板桩码头的结构形式在国外施工项目中日渐增多,码头的板桩墙与胸墙主要分为陆上施工与水上施工2种形式。陆上施工需要提前填筑围堰,施工措施费用较高且工期延长;水上施工胸墙工序繁琐且施工的安全风险较大、对工程的工期、质量造成一定影响。文章介绍了印尼奥比岛Persada 6B泊位项目的板桩码头胸墙工艺,该项目使用了力矩平衡式底模设计,通过悬吊底模并整体安装的施工工艺,避免了水下焊接作业,且对施工期间的底模力矩平衡条件进行了分析计算,工艺经过项目实践得以顺利实施。The structural forms of sheet pile wharves are increasing in foreign construction projects,and the sheet pile walls and breast walls of wharves are mainly divided into two types:onshore construction and over-water construction.Onshore construction requires early filling of cofferdams,which incurs high construction costs and prolongs the construction period;the over-water construction process of the breast wall is complicated and the construction safety risk is large,which has a certain impact on the project schedule and quality.This paper introduces the process of sheet pile pier breast wall for the Persada 6B berth project in Obi Island,Indonesia.The project uses a torque balanced bottom formwork design,which avoids underwater welding operations by suspending the bottom formwork and installing it as a whole.The torque balance conditions of the bottom formwork during construction are analyzed and calculated,and the process is successfully implemented through project practice.
