In practice, the numerical simulation of soil nailing wall is often performed to evaluate the performance and stability. Use one or two stairs, while in the metropolitan area, despite the space constraints, it is possible to reduce deformations and increase safety factor excavation nailing method that justifies the use of this technique is relatively new. In the present study investigated The effect on the stabilization excavation stairs by nailing taking into account the behavioral models Mohr-Coulomb soil and HS and HSsmal to Software finite element is discussed. Use one or two stairs ratio to the nailing vertical wall with regard to behavioral models Mohr coulomb and HS and HSsmall soil maximum of horizontal and vertical and horizontal deformations of the top edge of the excavation is severely reduced Also uses a two-stairs soil nailing safety factor in the wall, with all models of behavior is considered to increase the equally.
