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.
