水下隧道沉管法设计与施工关键技术
Key technology of design and construction on immersed tube tunnel
结合国内已建成的沉管隧道对沉管法施工干坞方案比选、管段及接头防水设计进行了探讨分析，对沉管法施工的关键技术如管段制作、管节浮运、沉放及水下对接和基础处理方法进行了归纳。
Combined with the built immersed tube tunnel, comparison and selection of dry-dock scheme, waterproof design of tube sections and joints are analyzed. The key technologys such as tube prefabrication, tube floating, tube sinking, jointing underwater and foundation treatment method are generalized.
