摘要

为探讨类似台海通道百米级超深水域条件下采用沉管隧道方案通过的可行性，调研国内外沉管隧道，特别是港珠澳大桥、深中通道，结合沉管隧道3大技术难题(管节接头、基础、浮运安装)，从方案设计、施工可行性出发，探讨在超深水域隧道本体结构、管节接头止水系统、基础和浮运安装船机装备的适应性。经过综合分析验证可知：通过重新设计GINA止水带，研发新型装备、工艺解决先铺法基础施工问题，研发新型测控系统及沉放系统解决管节沉放问题等，可以认为台海通道采用沉管隧道方案是可行的。

Abstract

The authors discuss the feasibility of immersed-tube tunnels in ultra-deep (over 100 m) water areas such as Taiwan Strait, and make a investigation on global immersed-tube tunnels such as the Hong Kong-Zhuhai-Macao bridge and the Shenzhen-Zhongshan link. Based on three major technical challenges of immersed tube tunnels, i.e., element joint, foundation, element floating and installation, the adaptability of element structure, joint sealing system, foundation, and floating and installation ship machinery equipment are discussed from the perspectives of scheme design and construction technology. The results demonstrate that the immersed-tube tunnels are feasible for crossing Taiwan Strait by redesigning GINA waterstops, developing novel equipment, measurement and control systems, and sinking systems.

Key words： Taiwan Strait channel; ultra-deep immersed-tube tunnel; joint waterproofing; foundation treatment; element sinking and installation
