Abstract


Soil nailing is a method of reinforcing the soil with steel bars or other materials. The purpose is to suppress the tensile and shear stresses in soil and restrain its lateral displacements. The nails are either placed in drilled bore holes and grouted along their total length to form 'grouted nails', or simply driven into the ground, called as 'driven nails'. The technique helps stabilization of both natural slopes and vertical or inclined cuts. Many investigators ([1]-[6], [8], [9]) have proposed methods for investigating the stability of vertical/nearly vertical excavations. The Basic aim of this study is to find out the behaviour of the nailed cuts in cohesive - frictional soil. The study also helps in deciding the elementary profile of nails in the design and also states the effect of consideration of seismic coefficients on the value of factor of safety for the design of nailed vertical cuts.
