108141 - Research on Strengthening Complex Foundations by Combining Multiple Foundation Treatment Methods 

With the rapid development of the economy, the competition among ports is becoming more and more fierce, and the requirements for port yards are becoming higher and higher. However, due to its complex soil deformation, practicality and theoretical lag, how to deal with the reinforcement of complex foundations in a small area has always been a difficult problem. Multiple options for Foundation reinforcement exist; but the options vary in efficacy. There is no shortage of engineering examples of failures with serious consequences.

The total area of a container yard is 789,000 m2, and the formation and the boundary of the land area are very complicated. The formation contents of the land area include: exploded rock surface, backfilling rocks and backfilling powder sand on the natural foundation. As the superstructure of this project is a container yard with large concrete slab structure, the requirements for the bearing capacity and settlement of foundation are very high. Therefore, the foundation treatment is an extremely important part of the project construction. Whether the foundation reinforcement method is properly selected will have a great impact on the cost and duration of the whole project.

This study focuses on the comprehensive utilization of multiple foundation treatment methods in the complex foundations reinforcement by exploring the practical solution of a composite foundation reinforcement project for a container yard in the high seas region. After several tests, it can be found that the effect of foundation reinforcement exceeds the usage requirement, and the remaining settlement meet the requirements.
