Abstract :
    Nailing is one of the soil stabilization systems that has recently been expanded. The method of using the nailing method is based on the arming of the soil mass using sewage of the soil mass with steel tensile barriers close to each other. Using this method increases the shear strength of the soil mass and also reduces the slip strength at the level of rupture. In this research, the effect of the angle of the Nile and the interaction of soil and Nile on horizontal displacement and vertical displacement and tension in an earth s girdle have been investigated and the results of a physical experimental model have been used whose numerical model is modeled and calibrated in plaxis software, and in A row of nails and two rows of nails have been investigated. From the results of the study, it can be concluded that with increasing the angle of the nile, the horizontal displacement and vertical displacement of the verge of the nile and the two rows of the nails are reduced, and also the tropical sandstone stress decreased with increasing the angle of the Nile in a row of Nile And has increased in two rows of Neil. Also, with the increase of soil and nil interaction in each case, horizontal displacement and vertical displacement increased, and the tensile stress in a row of Nile decreased and was increased in two rows of Nile.
