Abstract: In the shear failure mode, the particles in contact with each other in aperture area and particles in touch with geogrid are effectively resisting shear force during the shear test. The void area at the interface is not offering any resistance, only particles in contact with each other or with geogrid are contributing the resistance.The particle size and their associated voids play an important role in the dissipation of energy under the loading of granular materials. Numerous laboratory, numerical and analytical tests has been performed by many researchers to determine the influence of particle size and void ratio on the shear interface mechanism. An equation is formulated considering the actual area of contacts with dry density as variable for the shear resistance at the interface.

Keywords: combined shear resistance; interface shear ;geogrid-soil; passive resistance;shear mode;soil gradation; transverse ribs.
