Combined pile-raft and raft foundation modelling and design for three distinct office buildings in Lisbon, Portugal
Combined pile-raft and raft foundation modelling and design for three distinct office buildings in Lisbon, Portugal
In recent years many projects were designed using the Combined Pile-Raft Foundation (CPRF) concept. Combined Pile-Raft Foundations have a complex soil-structure interaction scheme including the pile-soil interaction, pile- pile interaction, raft-soil interaction, and finally the pile-raft interaction. Consequently, there is a need for 3D numerical models that can study this complex interaction. In this paper, several 3D models are presented and discussed for the founda- tion design of three office buildings, that were built using the Combined Pile-Raft and Raft Foundations solutions, near the right bank of the Tagus River in Lisbon, Portugal. The study was based on geotechnical information provided by the site investigation and by Static and Dynamic Load Tests on Driven Piles, both performed in several spots evenly distributed at the site. The developed 3D model was able to simulate the behaviour of the piled raft foundation system.
