Stability and deformation of geosynthetic reinforced soil retaining wall

This paper presents the results of a study to evaluate the displacement of a reinforced earth wall using a small model. The study involved two kinds of geosynthetic strips namely rubber and high density polyethylene (HDPE). A series of tests was performed using a moving wall model where strips reinforcement of width 50mm with varying lengths of 300mm, 400mm and 500mm could be tested in dry Aio sand. The results indicate that the wall displacement was greatly influenced by the tensile stiffess of the reinforcement. Furthermore, the strains measured along the strip provide useful information on the behavior of the strip when subjected to, firstly active force and later an additional pull-out force.
