Abstract :
    Arming of soil with the help of materials with high tensile strength. Effective method for protection of earth structures. goes. A number of walls in this study have been modeled using numerical software and have the desired confidence coefficient it is arrived. The content of this research is based on the federal letter and is intended to achieve the desired confidence level. Results It is shown that the factors affecting the achievement of the coefficient of reliability can be applied to the internal friction angle of adhesion soil And soil hardness. In this research, a numerical model is firstly modeled with and using the Paxis 2D software. And compared with the FHWA method. In three models, the coefficients of confidence of 1.507, 1.28 and 1.59 is reached. These confidence coefficients can show us that the FHWA method is modeling The numerical value of the PLAXIS software, although different in the results, has different confidence coefficients, but In terms of regulations, the confidence coefficients obtained in both methods are acceptable. And that with the parameters The same geotechnical approach is required in both methods with the required reliability coefficients.
