The Influence of Raft Thickness on the Behaviour of Piled Raft Foundation

The behaviour of piled raft foundation is influenced by several factors such as the thickness of raft, the number of piles, the length of piles as well as the types of soil in which the foundation is inserted. The piled raft foundation in the article is derived from the Vietcombank Tower's foundation and is analyzed by CSI SAFE software. This numerical modelling is verified by comparing the monitoring result of settlement. Based on this model, the authors performed the different analyzes of the piled raft foundation by varying the amount of piles and the thickness of raft with the same condition of the ground and pile length. The results demonstrate that the choice of raft thickness is the main factor that affects the optimization of the piled raft foundation.
