摘要

摘要: 以横琴岛澳门大学新校区跨海隧道工程为研究背景，重点分析研究了滨海地区超深软土地质条件下的海上筑岛围堰超深基坑工程。介绍了该基坑工程的设计方案选型、施工工法工艺，并基于实测数据，对该工程基坑开挖全过程的围护结构变形规律进行了分析研究。其研究结果能够为今后滨海地区海上筑岛围堰超深基坑工程的设计、施工提供有价值的参考依据。

Abstract: By means of the island and cofferdam construction method, the ultra-deep foundation pit under ultra-deep soft soils in coastal areas is analyzed, based on the cross-sea tunnel project of the new campus of University of Macau on Hengqin Island. The design selection and construction method of the foundation pit are introduced. Based on the measured data, the deformation rules of foundation pit support system are discussed. It may offer valuable reference for the design and construction of ultra-deep foundation pits in coastal areas in future.
