Abstract

In engineering, a foundation is a crucial structural element that transfers load from a structure to the underlying soil. Foundation failure can have severe consequences, highlighting the need to understand and mitigate potential risks. To meet the growing demand for efficient and sustainable foundations, engineers are constantly exploring innovative designs that optimize material use while maintaining or enhancing load-bearing capacity. One such system that has gained popularity in recent decades is the piled raft foundation. This system offers a cost-effective and high-performance solution, particularly for challenging soil conditions. It is needed to highlight a general and broad information about this system including pros and cons, design criteria, soil-pile interaction as well as pile-raft interaction. So, this paper provides a comprehensive review of various design concepts for piled raft foundations, as proposed by different researchers. the load-sharing mechanism within these systems was explained as well. The study reveals that several factors influence the load-sharing ratio, and that the raft component plays a significant role in reducing total and differential settlement
