摘要:

针对跨海水下隧道工程中人工岛建设的研究现状及主要问题,收集了典型的跨海水下隧道人工岛的工程实例,总结了跨海水下隧道人工岛的地基处理、围堰构建和填土加固的关键施工技术,指出软弱地基处理及填土加固方案组合和工序优化以及疏浚土在国内人工岛建设中利用较少是跨海水下隧道人工岛建设过程中两大主要问题；基于现有的人工岛建设技术,人工岛建设的未来发展方向是通过预制人工岛构件实现绿色快速筑岛。

Abstract:

In view of the research status and main problems of artificial island construction in the underwater tunnel engineering, this study collects typical engineering cases of artificial island in the underwater tunnel projects, and summarizes key construction technologies of foundation treatment, cofferdam construction and fill reinforcement of artificial islands. Two main problems in the construction process of underwater tunnel artificial islands were proposed: firstly, the combination of schemes and process optimization for the soft foundation treatment and the soil filling reinforcement; secondly, the utilization rate of dredged soil in the construction of artificial islands in China was relatively low. Based on the existing construction technology of artificial islands, the future development direction of artificial island construction is to achieve the green and rapid island building through prefabricated artificial island components.
