Macro-Mesoscopic Study of the Interface between Sand and Geogrid
The visual pullout model box was built, and a series of geogrid pullout tests were conducted to study the micro-macro feature of the soil/geogrid interface. Associating with image visual tracing technique and non-target measuring technique, displacement and shear strain field in the process of pullout was obtained. The results show that the apparent friction coefficient was related with the vertical stress, the sand particles show high gradient changes of displacement and concentration of shear strain in the interface region; the thickness of standard soil/geogrid interface is 6.5 times the average particle size. The study results contribute to providing a new understanding for more in-depth study on the mechanism of the reinforcement interface.
