Abstract: Many departments where embankments are constructed for highways and railway tracks face the problem of failure of embankments. Safety of the human beings and infrastructure is endangered because of slope failures resulting in loss of life and loss of investment which is a matter of concern in the Government bodies, and disaster relief authorities. These failures impede the socio-economic development of the country. This comprehensive study includes slope stabilization by using soil nails known as reinforcement in soil slopes. In this paper, analysis is carried out for slope stability by ASD (Allowable Stress Design) methods and LRFD (Load and Resistance Factor Design) for various nails inclinations to find out the better nails inclination for better slope stability. By using ASD and LRFD analytical methods the maximum FOS is observed in the range of 150 to 250 nails inclination.

Keywords: soil nailing, slope stability, ground improvement, reinforced soil, embankment, nail inclination.
