Abstract
Simple numerical codes for the analysis of soil structure interaction in the case of piled raft foundations are available. A proper idealisation and geotechnical quantification of the subsoil profile is of main concern. Firstly, recent research work on the problem of piled foundations embedded in layered soils is reported. In the second part of the paper innovative design criteria for piled rafts are discussed. It is argued that for a proper application of innovative concepts the safety factor of a piled raft has to be defined. To this aim 3D finite element predictions of the ultimate vertical load of a piled raft will be presented.File in questo prodotto:
