Abstract

Various constitutive models for the contact between soils and structural elements have been proposed in the past. These models are important for holistic modelling geo-structures like piles, anchors, retaining walls etc. Different soil-structure interface models using different mathematical formulation have been defined and some of these are analyzed in this publication using a deterministic model quality approach. Experimental data from the literature serves as validation and verification for the models used in this paper. The different experimental data are related to Constant-Normal-Load and Constant-Normal-Stiffness interface tests carried out with the simple shear and direct shear interface apparatuses. These are the most appropriate experimental set up used for the realistic estimation of the displacement analysis of soil-structure interfaces. The paper concludes with benefits and drawbacks identified after the comparison.
