“…Their use is increasing due to regulatory requirements for their application in first-class roads, as well as their engineering advantages -lightness, durability, possibility of occupying large roof areas, easy installation, individual sizes, etc. however, its applications are limited because of the sizeable long-term deformation under constant loading and poor tensile strength [6] - [9].…”

“…However, the shear force at this point still does not reach the shear strength of the compartment, and thus some of the kinetic energy of the runoff is consumed (Zeng et al, 2017), and the undercutting ability is significantly weakened. In addition, under the combined actions of the friction force and the lateral restraint force generated by the side walls of the cell on the surface soil, the cohesion of the soil in the geocell is considerably stronger than that of the bare slope soil (Vibhoosha et al, 2021). The ability to prevent runoff erosion is highly improved, and thus, no rill is formed on the surface of the ephemeral gully, but only intermittent erosion, which is also one of the reasons for the reduction in erosion depth.…”

Investigating the effect of geocells on the erosion and deposition distribution of ephemeral gullies in the black soil area of Northeast China can provide a scientific basis for the allocation of soil and water conservation measures in ephemeral gullies. In this study, an artificial simulated confluence test and stereoscopic photogrammetry were used to analyze the distribution characteristics of erosion and deposition in ephemeral gullies protected by geocells and the effect of different confluence flows on the erosion process of ephemeral gullies. Results showed that when the confluence flow was larger, the effect of geocell was more evident, and the protection against ephemeral gully erosion was stronger. When the confluence flow rates were 0.6, 1.8, 2.4, and 3.0 m 3 /h, ephemeral gully erosion decreased by 37.84%, 26.09%, 21.40%, and 35.45%. When the confluence flow rates were 2.4 and 3.0 m 3 /h, the average sediment yield rate of the ephemeral gully was close to 2.14 kg/(m 2 •min), and the protective effect of ephemeral gully erosion was enhanced. When the flow rate was higher, the surface fracture of the ephemeral gully was more serious. With an increase in confluence flow rate, the ratio of erosion to deposition increased gradually, the erosion area of ephemeral gullies was expanded, and erosion depth changed minimally. In conclusion, geocell measures changed erosion patterns by altering the rill erosion/deposition ratio, converting erosion from rill erosion to sheet erosion.

“…These studies have found that the mechanical properties of the grids, soil particle gradation, and particle size are the key factors that affect the geogrid-soil interface. However, most of the studies have been based on static loading conditions [7][8][9][10][11].…”

This paper presents the results of horizontal cyclic direct shear tests at the reinforced soil interface of a four-way polypropylene geogrid reinforced sandy soil. The influence of normal stress and shear displacement amplitude on the shear stress, shear stiffness, and damping ratio of the reinforced soil interface are evaluated by varying the normal stress and shear displacement amplitude. Dynamic shear characteristics of reinforced soil interface under normal constant load were investigated by using a large dynamic straight shear apparatus. Peak interface strength increases with increasing amplitude of normal stress and shear displacement amplitude. The larger the normal stress and shear displacement amplitude, the fewer cycles are needed to attain peak interface strength. At low-magnitude normal stress levels, the peak shear stress and shear stiffness tend to stabilize after an initial increase during the cycling process, and the damping ratio decreases and then stabilizes with the increase in the number of cycles; whereas when the normal stress level is high, the peak shear stress and shear stiffness increase and then decrease during the cycling process and eventually stabilize, and the damping ratio decreases and then increases and finally stabilizes with the increase in the number of cycles. Moreover, under the same number of cycles, the corresponding shear stiffness decreases with an increase in shear displacement amplitude, while the damping ratio increases.
