“…Geosynthetics are widely used as reinforcement in walls, slopes, weak foundations, and reinforced wall structures, where they are subjected to constant stress throughout their service life. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Polymers are viscoelastic materials, which components of geogrids, their creep properties affect the long-term performance of reinforced soil structures. [17][18][19][20][21][22][23] Thus, it is necessary to evaluate the long-term creep behavior of geosynthetics.…”

Only considered creep behavior of geosynthetics in the design and construction of reinforced structures, not that the creep behavior of reinforced materials considered geosynthetics-sand interaction under different loading levels. A series of creep tests on a geogrid under different loading levels were carried out through a self-developed test device. The long-term creep characteristics of the geogrids under different loading levels were analyzed. The results showed that: Compared to sand constraint condition, under the same loading level, the creep rate under non-constraint condition is about 1.1 times. After the creep time over 400 h, the strain growth rate tends to be a constant value for sand constraint condition, which needs 700 h for non-constraint condition. Creep deformation mainly occurs near the pullout endpoint of the geogrid, and the deformation of each strain measurement zone is reduced from the tensile end to the fixed end of the geogrid.

“…Soil reinforcement can consist of a wide range of materials such as polymeric geosynthetics [1]. Geosynthetics have been used in various forms especially in two-dimensional (2D) planar form [4–6] (geogrid, geotextile, and geonet) or the three-dimensional (3D) form [3,7–9] (geocell). They are also used as long fabric or the continuous insert form (sheets, layers, strips), and as randomly oriented discrete inclusions (short cut fibers) [10].…”

This study introduces the tubular braided structure as a new geosynthetic material for sand reinforcement. The performance of a tubular braid under the influence of similar soil–reinforcement interaction mechanisms has been investigated to emphasize the effect of the reinforcement form on the performance of the reinforced soil composite. For this purpose, three series of interaction element tests including direct shear tests, pull-out tests, and soil stress control tests were conducted on the unreinforced and reinforced sand. Finally, the overall performance of the reinforced foundation bed with the planar and tubular reinforcing textile (with similar materials, properties, texture, and areal density) was evaluated through a series of standard plate load tests. The results indicated that the performance of the sand-braid composite was better compared to the similar typical planar reinforcement, except for the case of pull-out test. Tubular braid resulted in the enhanced shear strength of the reinforced soil composites, mobilization of the excess compressive stress in the enclosed soil inside the tubular braids, reduction in the vertical stress level of the footing model transferred down through the soil bed, the increase of the average bearing capacity of the footing model, and a significant reduction in the footing settlement.
