abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...

Fiber-reinforced soil is an excellent engineering material that has become a focus of research. Most studies on the conventional mechanical properties reinforced soil, such as its tensile, compressive, and shear strength, rarely study creep-related properties. However, when used backfill, creep effect should not be ignored. This explored characteristics mechanics in fiber-reinforcement mechanis...
