Effect of pile arrangement on long-term settlement and load distribution in piled raft foundation models supported by jacked-in piles in saturated clay

Soils and Foundations
When designing a piled raft foundation (PRF) on clay, it is essential to understand the time-dependent behaviors of the foundation. However, little attention has been paid to this issue.
