“…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]. At the same time, some valuable results were obtained by a series of pullout tests.…”

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.

“…Based on the linear elastic theory and under the same normal pressure, Yuan [ 13 ] proposed that the tensile force was a function of the reinforcement stiffness, the shear stiffness of the reinforcement–soil interface, the embedded length of reinforcement, and the pull-out displacement. Cui et al [ 14 ] proposed a simplified theoretical model to investigate the hardening behavior of geobelts in pull-out tests; Xu et al [ 15 ] conducted pull-out tests to analyze the interface properties of steel fibers embedded in an polyester and epoxy matrix, and the experimental results were fitted to an analytical model to obtain the interface shear strength. Huang et al [ 16 ] theoretically derived a nonlinear interface model reflecting the effect of residual shear strength at the anchorage interface based on the double exponential curve interface model.…”

Considering the strain-softening characteristics of the pull-out interface between geotextiles and tailings; to determine the interface interaction characteristics, this paper proposes a trilinear shear stress displacement softening model of geotextile-reinforced tailings. The obtained nonlinear governing equations were dimensionless, which were expressed in finite difference form. The results indicated that an accurate numerical solution could be obtained within a reasonable calculation time by discretizing the reinforcement length into 300 units. Three new dimensionless interaction terms, namely, the relative stiffness α, relative displacement β, and relative interface shear stiffness η of the reinforcement-tailings interaction, were introduced. In addition, an estimation method based on the approximate value of the relative stiffness α of the reinforcement-soil interface in the low-tensile-force displacement range was proposed. The interface shear stress range according to parameters α, β, and η was parameterized, and the normalization relationship between the tensile force and pull-out end displacement was determined. The numerical values calculated by the model were compared with the pull-out test results, demonstrating that the proposed model can accurately predict the pull-out behavior of the extensible reinforcement.

“…e results showed that the antivibration performance of soil is improved with an increase in the number of reinforced layers. Tests have been conducted to explore the interaction between geosynthetics and soil [24][25][26][27][28][29], [30] and mathematical models have been proposed [31][32][33][34][35][36][37]. Although model tests can help in understanding the dynamic response characteristics of reinforced soil, numerical simulation results are more intuitive [38][39][40][41][42][43][44][45][46].…”

To explore the reinforcement effects of different reinforcement methods, kraft paper was used as reinforcement material, and shear tests were carried out in sand to study the reinforcement effects of kraft paper perpendicular and parallel to the shear plane. The test results show that the two reinforcement methods can effectively improve the strength of sand and the orthogonal reinforcement form is more superior. The existence of reinforced materials greatly improves the cohesion of sand, but does not significantly improve the internal friction angle. The width of reinforcement material has little effect on the reinforcement effect and shows different variation laws under different reinforcement forms.
