Abstract

Abstract: A simplified theoretical method to predict the interlocking forces in the geogrid reinforcement is proposed in this paper. Through a simplified approach of the aggregates and geogrid interactions, a unit interlock mode is proposed to simulate the two relative movement modes between the soil backfill and the geogrid. These two basic movement modes are: translation and rotational move. The ultimate tensile forces of the geogrid as well as the unit interlocking forces are derived.
