چکیده مقاله
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 differentconstruction 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
