Load-strain-displacement response of geosynthetics in monotonic and cyclic pullout

Abstract: Mobilization of the pullout resistance of geosynthetics in monotonic and cyclic modes is described from both displacement-and load-controlled tests performed at normal stresses in the range 4-17 kPa. The tests were performed on three geogrids and two geomembranes embedded nearly 1.0 m in a uniformly graded sand. Results for load-controlled tests at a constant rate of 0.25 kN/(m⋅min -1 ), followed by several series of load cycles of increasing amplitude, are compared with displacement-controlled tests at a cons… Show more

“…The interaction between the geosynthetic reinforcement and the backfill material is of critical importance for the safe design and adequate performance of geosynthetic-reinforced structures, such as walls, slopes and bridge abutments [26,27]. Various test methods have been used by numerous researchers over the last decades to characterise soil-geosynthetic interaction, such as the direct shear test [28][29][30][31], inclined plane test [32][33][34][35], pullout test [36][37][38][39][40] and in-soil tensile test [41], each of which allows simulating a different type of deformation at the backfill-reinforcement interface. For instance, the direct shear test is commonly used to analyse soil-reinforcement interaction when sliding of the backfill on the geosynthetic surface is anticipated, whereas the pullout test simulates the interaction between the backfill and the reinforcement in the anchorage zone of geosynthetic-reinforced soil walls and slopes (i.e., beyond the hypothetical failure surface).…”

“…Several experimental methods have been developed for the analysis of soil-geosynthetic interaction, including direct shear tests, pullout tests, in-soil tensile tests and inclined plane tests (e.g. Alfaro et al 1995;Lopes andLadeira 1996a, 1996b;Raju and Fannin 1998;Pinho-Lopes and Lopes 1999;Costa-Lopes et al 2001;Ramirez and Gourc 2003;Mendes et al 2007;Liu et al 2009;Ferreira et al 2012Ferreira et al , 2013Ferreira et al , 2014Vieira et al 2013;Lopes et al 2014). Among them, pullout and direct shear tests are the most commonly used.…”
