Resumen: This paper highlights a computational framework for the numerical analysis of fluid saturated soil-structure interaction problems. The Particle Finite Element method is used to solve the linear momentum and mass of the mixture balance equations at large strains. The robustness and accuracy of the proposal is numerically demonstrated by means of the analysis of benchmark examples. Indeed, in the oedomeneter test example, it is shown that using a large deformation theory may reflect results that are artificially excluded by the linear theory. The paper concludes with a parametric analysis of a cone penetration test, where the influence of the contact roughness and permeability to the shaft friction and cone resistance are assessed.
