“…Hence, the friction characteristics [22,23] of the interface between soil and geogrid reinforcement are one of the important factors to be considered in the design and stability analysis of GRS structures. e pullout test [24][25][26] is an effective and also commonly used method to investigate the interaction of the interface between soil and reinforcement. In order to simulate the interaction process and further understand the mechanical behavior and deformation characteristics of geogrid reinforcement, many laboratory experiments have been performed by several authors [27][28][29].…”

This paper describes a series of laboratory pullout tests that were performed to investigate the pullout behavior of high-density polyethylene (HDPE) uniaxial geogrid subjected to static and dynamic loading. Pullout tests were conducted on HDPE geogrid reinforced coarse sand under normal static loading (60–300 kPa), dynamic loading with different amplitudes (20, 40, and 60 kPa), and different frequencies (2, 4, and 6 Hz) by using the newly developed pullout apparatus. The results indicated that the pullout resistance of geogrid presented different growth patterns with the increase of normal loads under static loading. The amplitude and frequency both had significant effects on the interaction between reinforcement and soil, and the increment of the pullout resistance was 0.6 kN and 0.3 kN, respectively. The effect of dynamic loading on the soil-geogrid interface can be gradually equivalent to that of static loading corresponding to the balance position of dynamic loading with the increase of frequency compared with the static loading. The results of this study are helpful for the selection of the strength of the reinforcement in different locations and to simplify the study on the stress of reinforcement in reinforced soil structures under traffic loads.

“…The results can be used to establish stability ratings based on the peak strains measured [ 114 ]. Soil–geogrid interaction was also studied with FBG sensors [ 118 ]. Density, initial stress, and boundary conditions were assessed and showed the influence of the boundary on the peak stress propagation from the load applied to the boundary before the pullout.…”

“…Density, initial stress, and boundary conditions were assessed and showed the influence of the boundary on the peak stress propagation from the load applied to the boundary before the pullout. Higher density and initial normal stress result in a slower progression of the shear stress towards the boundary [ 118 ]. Numerical modeling and experimental results show that the radial pressure in some sections acting on a buried pipe can also be measured using activated geogrid [ 119 ].…”

Geogrids are a class of geosynthetic materials made of polymer materials with widespread transportation, infrastructure, and structural applications. Geogrids are now routinely used in soil stabilization applications ranging from reinforcing walls to soil reinforcement below grade or embankments with increased potential for remote-sensing applications. Developments in manufacturing procedures have allowed new geogrid designs to be fabricated in various forms of uniaxial, biaxial, and triaxial configurations. The design flexibility allows deployments based on the load-carrying capacity desired, where biaxial geogrids may be incorporated when loads are applied in both the principal directions. On the other hand, uniaxial geogrids provide higher strength in one direction and are used for mechanically stabilized earth walls. More recently, triaxial geogrids that offer a more quasi-isotropic load capacity in multiple directions have been proposed for base course reinforcement. The variety of structures, polymers, and the geometry of the geogrid materials provide engineers and designers many options for new applications. Still, they also create complexity in terms of selection, characterization, and long-term durability. In this review, advances and current understanding of geogrid materials and their applications to date are presented. A critical analysis of the various geogrid systems, their physical and chemical characteristics are presented with an eye on how these properties impact the short- and long-term properties. The review investigates the approaches to mechanical behavior characterization and how computational methods have been more recently applied to advance our understanding of how these materials perform in the field. Finally, recent applications are presented for remote sensing sub-grade conditions and incorporation of geogrids in composite materials.

“…Note that negative skin friction develops at the column shaft, increasing the stress and compression on the column and reducing the stress and compression in the surrounding soil. The deformation shape of the latter is hard to determine and is influenced by certain factors, such as soil structure interactions (Zhou and Yin, 2008;Yin and Zhou, 2009;Su et al, 2010;Zhou et al, 2011;Hokmabadi et al, 2014;Suleiman et al, 2016;Meguid et al, 2017;Yu and Bathurst, 2017;Zhu et al, 2017;Jing et al, 2018;Wang et al, 2018b) and constitutive models adopted for subsoil (Yin et al, , 2010a(Yin et al, , 2010b(Yin et al, , 2011a(Yin et al, , 2011bSexton et al, 2016;Yin et al, 2017). Alamgir et al (1996) innovatively proposed a deformed shape function to investigate the performance of a column-reinforced foundation, which is applied here for this purpose.…”
