Stability Computations in Nailed Slopes The paper pertains to the development of generalized procedures for stability computations for nailed slopes considering both internal and oveall equilibrium where in the slice can be either vertical or inclined. It has been observed that consideration of internal equilibrium does not result in a large deviation in the factor of safety values compared to those based on overall equilibrium only.Several methods are being used for the analysis and design of nailed slopes,such as the Davis method (Mitchel and Schlosser, 1982), the German method (Stoker et .1979), the french method (Schlosser, 1982), the method developed by Gassler and Gudehus (1981) and the kinematic limit analysis approach (Juran,1990).The nails can be placed either horizontally or inclined. Lesniewska (1992) has shown that inclination of reinforcement plays a significant role in modifying the stability of nail structures. Optimal placement of reinforcement for minimizing cost of construction has drawn the attention of researchers. Analysis of the reinforced slope with inclined slices is likely to be better suited and computationally less involved becasue in this athe slices can be so aligned that it avoids the possibility of intersections of the nails with the slice interfaces.Increase or decreas in nails angel whit horizon and cohession coefficient of soil and spacing of nails cuese the variations of safety factors.In this research we have studied the variations of safety factor.
