An experimental program was undertaken to study the effects of glass fiber reinforcement on the shear strength characteristics of a locally available sand. Fibers up to 4% was mixed uniformly with the sand and then compacted into triaxial test specimens having soil relative densities ranging from 35 to 85%, prior to testing. The effects of fiber content, soil relative density and confinement pressure were investigated. The results indicate that with the increase of relative density, the stiffness, peak stress and residual stress of the reinforced sand have also increased. The fibers have induced significant apparent cohesion to the sandy soil up to 3% fiber content. This has led to increase in energy absorption capacity indicating improvement of bearing capacity of the soil. The failure modes of the specimens indicate that the fibers have restricted the bulging and shearing zones of specimens compacted at 35 and 85% relative density, respectively.
