     soil nailing is the technique where in-situ ground is reinforced by the insertion of tension-carrying soil nail. the soil-nail interface shear resistance plays an important role in determining the stability of nailed cut. the effect of grout properties is investigated to evaluate the pullout resistance of soil nail. a series of pullout tests were performed at four different construction sites. three-dimensional (3-d) finite element (fe) model using the abaqus code was developed and nonassociated elastic-plastic soil constitutive model using the mohr-coulomb failure criterion was employed to simulate the behavior of soil and grout in pullout test procedure. the mohr-coulomb failure criterion parameters of grout were determined by comparing the simulated results with pull-out test measured datas, and then the influence of these parameters were studied on the pull-out resistance of soil nails.
