| Abstract: | Soft soils are well known for their low strength and high compressibility. Several techniques, including reinforcement, are
commonly used to increase the strength and decrease the deformation of this kind of soil. This paper presents the results
of an investigation into the effects of fiber on the consolidation and shear strength behavior of a clay soil reinforced with
nylon fibers. A series of one dimensional consolidation and triaxial tests were conducted on samples of unreinforced and reinforced
clay with different percentages of randomly distributed nylon fibers. The results show that the preconsolidation pressure
decreases and the coefficient of swelling and compression generally increase with increasing the fiber content. Furthermore,
the addition of the fiber leads to a significant increase in shear strength and friction angle of the natural soil. |
