The Effect of Soil Parameters on mechanical Behavior of Soil Nailed Slope

Due to the participation of a large number of factors involved, one of the complex problems in geotechnics is stabilized soil slope stability analysis. We aim to present the results of investigations on the safety factor (FOS), nail force and displacement of soil slopes reinforced with nailing. In this research, a numerical study was followed by presentation a novel method, based on evolutionary polynomial regression (EPR) for capturing nonlinear interaction between various parameters of FS on the nail-soil slope for 65 cases. In order to attain the most effective factors on FOS, soil nail’s force and displacement, the cosine amplitude method (CAM), is considered.
