Technical Challenges in the Artificial Island and Immersed Tunnel Works of Hong Kong-Zhuhai-Macao Bridge Project
(1. Shenzhen-Zhongshan Link Administration Center, Zhongshan 528400; 2. The Hong Kong University of Science and Technology (Guangzhou), Guangzhou 511455)
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 offshore operations risks, high construction standards, and tight schedules. It has become the longest highway immersed 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 concept 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 settlement control of immersed tunnel in deep soft soils, and prefabrication of tunnel elements in factory. These achievements have strongly supported the construction of the artificial island and tunnel project, laid the foundation for subsequent 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.
