This paper presents a quantitative analysis of the interaction between soil, structure and friction piles located in a consolidating clayey soil using the Finite Element Method (FEM). The consolidation process due to the weight of the structure and to a pumping-induced decrease in pore water pressure is simulated. The evolution of stresses developed within the soil and at the interface between pile and soil is evaluated. Progressive increase of soil strength due to consolidation is taken into account. The analysis performed provides valuable insight into the complex interaction phenomenon between soil, piles and structure and suggests some important new elements to be taken into account in the design of friction piles for this condition.
