Abstract: Soil reinforcement technique is one of the most popular techniques used for improvement of poor soils. Metal strips, synthetic geotextiles, geogrid sheets, natural geotextiles, randomly distributed, synthetic and natural fibers are being used as reinforcing materials to soil. Further, the soil reinforcement causes significant improvement in tensile strength, shear strength, other properties, bearing capacity as well as economy. This is a relatively simple technique for ground improvement and has tremendous potential as accost effective solution to many geotechnical problems. The objective of the present investigation is to determine the effect of introducing coir mat reinforced soil layer over soil stratum and effect of size of the opening of coir mat on shear strength characteristics of sand will be analysed.

Keywords: Soil reinforcement, Shear strength, Coir mat
