Abstract	The study in the micro-mechanical behaviour on the contact interface is significant to understand the mechanism of the interaction between the soil and the structure. It is also the foundation for the interface constitutive modelling through the micro-mechanical approach. Existing researches majorly rely on phenomenological models, which characterize the constitutive behaviour on the interface according to macroscopic observed phenomena. This kind of model, such as the zero-thickness contact model (Goodman et al., 1968) and the thin layer element model (Desai, 2013), is unable to well explain the micro-physical process on and around the interface under shearing. Since the soil is a kind of granular material, the macroscopic behaviour of the interface layer (the soil layer near the interface) can be basically attributed to the movement, rotation and breakage of soil particles. Discrete element method (DEM) is, therefore, employed to investigate the distribution and the evolution of the micro-structure in the interface layer. A soil-structural interface shear test (as shown in Figure 1) is performed, as a rolling resistance is imposed between spherical particles to reduce the particles’ rotation. Three interests are held in this work: (1) the effect of the relative roughness of the
