... in-soil stiffness of the different geosynthetics. A nonwoven geotextile, a woven geotextile and a geogrid were tested under sand and gravel confinement. For all reinforcements used in this study, tests showed that reinforcement in-soil stiffness increases under soil confinement. The influence...

... to have different accuracy. This paper revisits the problem of geosynthetic-reinforced fills over voids from a probabilistic point of view for reinforcement tensile strain, tensile strength, and geosynthetic stiffness limit states. Particular attention is paid to the method used to select the isochronous...

...F. Song; W. Chen; Y. Nie; L. Ma Cellular geosynthetics have been widely used in engineering practices for their enhanced confining effects. However, limited research has been reported on methods of evaluating the required stiffness and strength of cellular geosynthetics based on the strength...

... expression. It was shown that the newly developed expression can predict the G_max of sand-fibre mixtures with an accuracy of around ±20%, with the error being limited to ±10% in the majority of the cases. geosynthetics laboratory tests stiffness 21 05 2018 06 09 2018...

... in the literature, the creep rupture response of the geotextile changed after installation damage. When tested under similar creep loads (fraction of the sample tensile strength), both geosynthetics exhibited reduced potential for creep rupture and smaller strains at the end of primary creep. Changes in stiffness...

...J. C. Lopera Perez; C. Y. Kwok; K. Senetakis This study presents a series of discrete element method (DEM) simulations consisting of mixtures of stiff (sand) and soft (rubber) particles, subjected to monotonic triaxial shearing under constant volume at very small strains where pure elasticity...

... geotextile were monitored for comparison purposes. The unconfined tensile stiffness of the nonwoven geotextile was three times smaller than that of the woven geotextile. This allowed direct evaluation of the effect of soil confinement on geotextile stiffness. Instrumentation was used to measure face...

... measured reinforcement strains to load using properly selected reinforcement stiffness values. The loading of the geosynthetic in the field can be simulated in the laboratory using creep, relaxation, and constant-rate-of-strain tests. It was found that in-isolation creep stiffness data is sufficiently...

... data also provides a baseline against which new design methods can be validated. In this paper, loads in soil reinforcement layers from 16 full-scale geosynthetic wall case histories were estimated from strain measurements and converted to load through the stiffness of the reinforcement material...

... interface relationship between shear stress and shear displacement interaction. Such a description of interface strength and stiffness characteristics is needed in analytical models used to predict a displacement response of geosynthetic-reinforced soil structures. Due to the extensibility of geosynthetics...
