Present study undertakes potential parametric optimization in soil nailing by considering soil nail interaction and back analysis of the pull-out strength of nail using Finite Element Analysis using PLAXIS 2D. Soil nailing as a construction practice has turned into a prime earth retention and slope stabilization technique.

Results suggest that the observed trend with reduced nail length patterns caused mild increment in the serviceability conditions like horizontal deformation, but the results were observed to be within permissible limits in the ultimate limit state. Further, dynamic analysis was undertaken to ensure the seismic stability considering the reduced nail length pattern using FHWA guidelines and the numerical approaches like finite element and limit equilibrium methods. The observed trend of results has been further validated using Limit Equilibrium Analysis.
With PLAXIS you can either apply a 'Static prescribed displacement' of 0.2 B and check the stress increase under your footing. The options available are: K0 procedure Field stress Gravity loading Groundwater flow only Plastic Consolidation Fully coupled analysis Safety Dynamic A.
