Abstarct: Soil nailing is one of the methods of arming the soil, using steel bars (nails) with intervals of less than a slope or deep inside the building from top to bottom. These bars are usually 20 to 30 mm in diameter reinforcement bars that are pre-drilled boreholes (diameter up to 15 cm) are associated with injection mortar Or using a blow drill at an angle of 10 to 15 degrees to the horizontal run. With this method we can shift to a low wall or concave slope stability and increased confidence. The advantages of this method can be of short duration and low cost compared to other methods of stabilizing named. In recent years, for reasons such as lack of sufficient experience in providing project design or inaccuracy in the implementation of cross walls are faced with destruction,This is a cause of concern and confidence is sent to this method .In this thesis, by studying several projects with Soil nailing wall retaining structure in which stabilization was carried out, it was determined that the walls collapsed due to various factors such as the soil is manually lack of studies Geotechnical design also in some cases, the lack of proper implementation is according to plan. Finally, this Soil model with finite element software PLAXIS real terms, if properly designed and implemented, excavation by using cross with confidence to remain constant. The results indicate the fact that the method of soil nailing facilities in the country, in some cases by providing needed confidence, more economical and faster than other methods, and can be used as an efficient and safe stabilization of interest Search.
