In view of the artificial island of the Hongkong—Zhuhai—Macao Bridge island and tunnel project, based on the steel cylinder cofferdam with water-stopping function and the condition of backfilling coarse sand on deep soft soil foundation, this paper proposes an innovative foundation reinforcement technology that simultaneously compacts the upper backfilling sand and improves the lower deep soft soil. Through the introduction of the design and construction scheme, the analysis of the foundation reinforcement mechanism, and finally through the foundation monitoring and testing, the results show that the effect of the foundation reinforcement is significant, and the new foundation reinforcement method can be a good reference for similar projects.
