Abstract Since the construction of immersed tunnels involves numerous procedures such as prefabrication, floating, transportation, immersion and underwater connections, a series of temporary auxiliary facilities are required for their installation. Based on domestic and international findings regarding temporary auxiliary facilities for the installation of immersed tunnels and referencing the design and construction of the Hong Kong-Zhuhai-Macau Bridge(HZMB) Immersed Tunnel Project, this paper systematically divides the temporary auxiliary facilities into different types and analyzes their features and the items needed to meet element construction requirements. The research results show that temporary auxiliary facilities for the installation of immersed tunnels involve numerous complex systems and professions, and the final scheme should be determined by considering the actual demands of the project with classified problems, facility features, capacity and engineering factors.
