摘　　要：深圳港盐田港区东作业区集装箱码头一期工程的东侧护岸采用重力式直立堤结构,由大型方块水下逐层安装成型,直立堤方块的安装精度及效率对整个码头工程的建设起到至关重要的作用。针对大型方块水下安装定位难、安装精度无法保证、效率低的问题,总结施工水域气候条件和水文条件,通过模拟分析及与类似工程方案研究比选,提出大型定位架及GPS(RTK)组合定位安装技术,实现了大型方块水下高精度、高效率、高质量的定位安装,圆满完成了大型方块水下定位安装任务。The eastern shore protection of the first phase of the Yantian Port area east operation area container terminal project in Shenzhen Port adopts a vertical embankment gravity structure,which is installed layer by layer underwater with large blocks.Therefore,the installation accuracy and efficiency of vertical embankment blocks play a crucial role in the construction of the entire terminal project.Aiming at problems that underwater installation positioning of large blocks is difficult,installation accuracy cannot be guaranteed,and efficiency is low,we summarize climate and hydrological conditions of the construction water area,and propose the large-scale positioning frame and GPS(RTK)combined positioning and installation technology by the simulation analysis and similar engineering scheme research and comparison.The technology achieves high-precision,high-efficiency,and high-quality underwater positioning and installation of large blocks,and is used to successfully complete the task of underwater positioning and installation of large blocks.
