PLAXIS 3D: Analysis of Combined Pile Raft Foundations (CPRF)

The limitations associated with conventional raft and pile foundations, particularly in modern infrastructure projects such as high rise buildings, bridges can be effectively addressed through the use of Combined Pile Raft Foundations (CPRF). In this foundation system, the raft and piles act together to share structural loads, reduce settlement, and enhance overall foundation performance, potentially resulting in more efficient and economical foundation solutions.

This comprehensive course on the analysis of CPRF using PLAXIS 3D is designed for practicing geotechnical and structural engineers, students, and research scholars. It provides a systematic and in-depth approach to developing realistic three-dimensional finite element models of CPRF with particular emphasis on accurately representing soil–pile–raft interaction. The course also presents a critical evaluation of PLAXIS 3D analysis results, enabling participants to assess CPRF performance using key indicators such as settlement reduction and load-sharing ratio. Emphasis is placed not only on developing the numerical model but also on interpreting and critically evaluating the results to gain meaningful insights into foundation behavior.

Upon completing this course, participants will be better equipped to use PLAXIS 3D as a powerful finite element analysis tool for addressing practical foundation engineering problems involving CPRF in critical structures and developing technically sound, efficient, and economical foundation solutions.
