摘　　要：港珠澳大桥通车后,沉管隧道目前已成为实现海上通途的工程方案选择之一,对于投资方和社会效益方面,工期是比较受关注的因素。通过收集港珠澳大桥、深中通道等项目的施工信息,结合外海沉管隧道施工关键线路梳理,以沉管浮运安装为主线,从人工岛止推段、沉管预制和最终接头等方面提出了快速完成外海沉管隧道施工的工期策划相关建议,可为后续外海沉管隧道施工提供参考。After the opening of the Hongkong-Zhuhai-Macao Bridge,the use of an immersed tube tunnel has emerged as one of the engineering options for establishing a fixed link.The construction duration has become a matter of significant concern for both investors and social benefit.By collecting construction information from projects such as the Hongkong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Link,and combining with an analysis of the critical routes for the immersed tube tunnel in open sea,taking the floating installation of immersed tubes as the main line,the suggestions for the expedited completion of the construction duration planning of the immersed tunnel in open sea were proposed from the aspects such as the artificial island stop-retreat section,prefabrication of immersed tubes,and the closure jointing process,which can provide reference for subsequent construction of immersed tunnels in open sea.

关 键 词：沉管隧道 沉管预制 沉管对接 最终接头 工期 先行工程
