摘要
港珠澳大桥岛隧工程是全桥项目的控制性工程,面临地质条件差、海上作业风险高、建设标准要求高和工期紧等多方面困难,建成后为目前世界最长的公路沉管隧道.2018年港珠澳大桥正式通车,2023年主体工程通过竣工验收,藉此再次梳理港珠澳大桥建设期面对的困难和技术挑战,大桥建设者秉承建设理念,以科研技术管理为抓手,通过科研与实践形成了海中人工岛快速成岛、深厚软弱土沉管隧道地基基础处理与沉降控制、工厂化管节预制等多项关键技术.其成果有力支撑了岛隧工程建设,为后续大型越江跨海岛隧工程建设奠定了基础,为世界跨海岛隧工程建设贡献了中国智慧.
Abstract
The artificial island and immersed tunnel works of the Hong Kong-Zhuhai-Macao Bridge project is the controlling works of the entire bridge project,facing various difficulties such as poor geological conditions,high off-shore operations risks,high construction standards,and tight schedules.It has become the longest highway im-mersed tunnel in the world after completion.The Hong Kong-Zhuhai-Macao Bridge was officially opened in 2018,and the main project passed the completion acceptance in 2023.This paper re-examines the difficulties and technical challenges faced during the construction of the Hong Kong-Zhuhai-Macao Bridge.Adhering to the construction con-cept and focusing on scientific and technological management,the bridge builders formed several key technologies through research and practice,such as rapid artificial island formation in the sea,foundation treatment and settle-ment control of immersed tunnel in deep soft soils,and prefabrication of tunnel elements in factory.These achieve-ments have strongly supported the construction of the artificial island and tunnel project,laid the foundation for sub-sequent large-scale river and sea-crossing artificial island and tunnel projects,and contributed Chinese wisdom to the construction of sea-crossing artificial island and tunnel projects in the world.
