摘　　要：随着“一带一路”、国家海洋战略、区域经济一体化战略布局发展,大批轨道交通、公路、铁路等大型基础设施工程面临着越江跨海的挑战。从南京长江隧道、上海长江隧道、武汉长江隧道的发端,通过引进、消化、实践、再创新盾构技术,促使我国水下盾构隧道技术进入快速发展阶段,一大批已建和在建超级水下盾构隧道工程极大推动了我国乃至世界水下盾构隧道技术的创新、发展和进步,在水下隧道盾构装备、设计、施工、运维等方面突破了一系列技术瓶颈。文章系统阐述了盾构技术三大要素及其内涵,即土水稳定、盾构设备及控制、结构安全与防水,分析了国内外超大直径水下盾构隧道技术现状与发展趋势,总结了近年来超大直径水下盾构隧道技术方面取得的重要创新成果,提出了大直径、长距离、高水压、复杂地质条件下水下盾构隧道工程的技术挑战、对策及工程应用前景。With the development of the"Belt and Road"Initiative,the National Maritime Strategy,and Regional Economic Integration Strategic Layout,a large number of rail transit,highway,railway,and other large-scale infra⁃structure projects are facing the challenge of crossing rivers and seas.Starting from the Nanjing Yangtze River Tun⁃nel,Shanghai Yangtze River Tunnel,and Wuhan Yangtze River Tunnel,by introducing,assimilating,practicing,and re-innovating of shield tunnelling technology,China′s underwater shield tunnel technology has entered a rapid development stage.A large number of completed and under-construction super underwater shield tunnel projects have greatly promoted the innovation,development,and progress of underwater shield tunnel technology in China and even the world,breaking through a series of technical bottlenecks in shield equipment,design,construction,opera⁃tion,and maintenance of underwater tunnel.The article systematically elaborates the three major elements of shield technology and their connotations,namely soil-water stability,shield equipment and control,structural safety and waterproofing,analyzes the current status and development trend of ultra-large diameter underwater shield tunnel technology at home and abroad,summarizes the important innovative achievements in ultra-large diameter underwa⁃ter shield tunnel technology in recent years,and proposes the technical challenges,countermeasures,and engineering application prospects of underwater shield tunnel with large diameter,long distance,high water pressure,and com⁃plex geological conditions.
