Abstract

Geogrid materials are frequently adopted as reinforcement to improve soil properties and geotechnical structural performance. One particular challenge facing engineers when designing soil reinforcement relates to the interface friction that is generated between soil and geogrid material. This aspect is not fully understood and current understanding is based on empirical data from laboratory pull-out interface tests. The objective of this paper is to investigate fundamental aspects of interface mechanics, evaluating the effect of parameters such as confining pressure, stiffness of reinforcement and transverse members of the geogrid stress to enhance design implementation. The research adopts a novel methodology of non-intrusive modelling using transparent soil in conjunction with laser aided imaging to visually observe soil geogrid interaction mechanics in a specially designed pull-out test apparatus.
