摘　　要：大型外海沉管隧道受其所在区域复杂的气候条件和作业环境的限制,与传统水运工程有很大的区别,沉管安装施工需要在水深、浪高、流急、流向旋转且无掩护的工况下完成作业,水力压接工艺作为沉放对接的关键环节,压接效果直接影响管节安装质量,以港珠澳大桥沉管隧道为例,对水力压接工艺及控制方法进行研究和说明。Large offshore immersed tunnel is constrained by the complex climatic conditions and the working environment where it is located,which is quite different from traditional water transport engineering.The construction work of element installation needs to be completed under conditions of deep water,high wave,rapid current,rotating water flow and without cover.Hydraulic press connection is the key process of sinking and connection which directly influences the quality of element completion.In this paper,HZMB immersed tunnel is used as the example to study and explain the process and control method of hydraulic press connection.
