“…Meanwhile, extensive experimental studies, including smallscale laboratory model tests and large-scale field tests, were conducted on geosynthetic reinforced soils by the authors in several research studies (Chen, 2007;Chen et al, 2007Chen et al, , 2009Sharma et al, 2009;Abu-Farsakh et al, 2007, 2008Chen and Abu-Farsakh, 2015) and also by other researchers around the world (e.g., Binquet and Lee, 1975;Huang and Tatsuoka, 1990;Adams and Collin, 1997;Tafreshi and Dawson, 2010;Bai et al, 2013;Demir et al, 2013;Chakraborty andKumar 2014, Miao et al, 2014;Naeini and Gholampoor, 2015). The influences of different variables and parameters contributing to the improved performance of reinforced soil foundation (RSF) were examined in these tests.…”

“…The results showed that the shear modulus of reinforced soils decreased in the low confining pressures (less than 100 kPa) and increased in the high confining pressures [15]. Naeini and Gholampoor (2014) carried out a number of cyclic triaxial tests on reinforced silty sand with geotextile. Their results showed that the dynamic axial modulus increased and the cyclic ductility of silty sand for all silt contents decreased with the increments of number of geotextile layers and confining pressure.…”

This research presents the dynamic behavior of fiber-reinforced soil exposed to freeze-thaw cycles. The series of dynamic triaxial tests were conducted on fine-grained soil mixed with different percentages of basalt and glass fibers subjected to freeze-thaw cycles. The results showed that after freeze-thaw cycles, with the addition of basalt and glass fibers, the damping ratio and the shear modulus increased at a constant confining pressure because of the increase of stiffness, but the shear modulus decreased with increasing shear strain. Moreover, the theoretical analytical formulations were developed to define for dynamic shear stress and dynamic shear modulus. The parameters were predicted by Hardin-Drnevich model and Kondner-Zelasko model. The shear modulus was expressed as a function of freeze-thaw cycles, fiber contents, confining pressure and initial water content. Finally, ten coefficients were calibrated by analyzing the experimental results and then employed to describe dynamic shear modulus of the fiber-reinforced soil.

“…Naeini et al [28] studied the interface shear strength of sand reinforced by geogrid which included the influence of sand silt mixtures on the shearing behaviour of reinforced silty sand. Furthermore, Naeini and Gholampoor [29] investigated the effect of geotextile layers on the cyclic behaviour of sand using triaxial apparatus. Test results indicated that liquefaction resistance increases with an increase of the number of geotextile layers.…”

This paper presents results of a series of undrained monotonic compression tests on loose sand reinforced with geotextile mainly to study the effect of confining stress on the mechanical behaviour of geotextile reinforced sand. The triaxial tests were performed on reconstituted specimens of dry natural sand prepared at loose relative density (Dr = 30%) with and without geotextile layers and consolidated to three levels of confining pressures 50, 100 and 200 kPa, where different numbers and different arrangements of reinforcement layers were placed at different heights of the specimens (0, 1 and 2 layers). The behaviour of test specimens was presented and discussed. Test results showed that geotextile inclusion improves the mechanical behaviour of sand, a significant increase in the shear strength and cohesion value is obtained by adding up layers of reinforcement. Also, the results indicate that the strength ratio is more pronounced for samples which were subjected to low value of confining pressure. The obtained results reveal that high value of confining pressure can restrict the sand shear dilatancy and the more effect of reinforcement efficiently.
