Three techniques for the study of soil structure interface properties; 3D roughness parameter; contact stress mapping; artificially manufactured sand

摘要

Three techniques for the study of the soil structure interface properties will be presented. The first technique involves the development of a 3D surface roughness parameter to evaluate the skin friction. The second technique is used to map contact stress concentrations at the soil structure interface using sensitive films developed for medical profession. The third technique is manufacturing artificial crushable sand at the desired properties to study static and dynamic interface behavior of soil and concrete. All of the techniques presented have a potential to understand the interface behavior in more detail. The techniques presented are implementable and practical.
