Abstract
Abstract
This paper reviews a number of methods for analysing and designing piled raft foundations. The methods fall into three categories: simplified hand calculation methods, approximate computer-based methods, and more rigorous numerical methods. These methods are then applied to two cases: a) a hypothetical case b) a published case study. It is demonstrated that there can be considerable differences among the predicted pile-raft responses from the methods considered, especially when the capacity of some of the piles is fully utilized, and the load-settlement behaviour is nonlinear. Cet article présente plusieurs méthodes permettant d’analyser et d’effectuer des fondations radiers-pieux. Les méthodes se divisent en trois catégories: les méthodes de calcul manuel, les méthodes informatiques approximatives, et les méthodes numériques plus rigoureuses. Ces méthodes sont appliquées à deux cas: (a) un cas hypothétique (b) une étude d’un cas publié. Il est démontré qu’il y a des différences considérables entre le comportement prévu par nos méthodes, particulièrement lorsque la capacité de quelques pieux est pleinement utilisée, et le comportement charge-déplacement est non-linéaire.
