Abstract
Soil reinforcement is one of the important techniques in geotechnical engineering, which is used to enhanced the engineering properties of soil. Soil reinforcement means, addition of natural or synthetic fibers to soil which act as tension members and sharing together with soil to sustain the applied loads. In soil reinforcement technique different types of fibers having different shapes can be used. The fibers used in soil can be having a shape like staples, chips, yarns, crumbs, bristles/hairs and other shapes. In the present time the using of fibers (especially natural fibers) in the earth construction works represent one of the cost-effective and environmentally friendly ground improvement techniques. The main objective of this paper, is to review the definition, mechanism, and application of using fibers in soil reinforcement through different scientific papers published in this subject. Further, the advantages and executive problems related to using fibers in soil reinforcement were discussed.
