Therefore, in this research, it is suggested to use a reinforced gabion wall in the surrounding environment of sanitary landfills. The implementation of this wall leads to a significant reduction in lateral movements of the landfill and finally a significant reduction in the rupture phenomenon in the landfill.<br>Also, the behavior of the retaining wall under dynamic load is a less well-known matter. In this study, using ABAQUS software, a number of finite element modeling has been done on a gabion retaining wall reinforced by geogrid. It has been used to perform parametric studies on the performance of retaining wall with gabion cover and geogrid network under different loads from zero to 120 kPa. Due to the similar mechanical behavior between waste and soil, researchers often use the proposed soil models to model the behavior of waste. The influential behavioral parameters of urban solid waste, equivalent to similar soil parameters including density, modulus of elasticity, Poisson's ratio and soil friction angle, are considered as the main variables. According to the obtained results, it was found that the Poisson's ratio parameter of the soil in low overburdens and the soil friction angle in higher overburdens are the factors that lead to more stress changes in the crown of the wall.
