Different Modeling Assumptions in Numerical Analysis of a Nailed Wall

Abstract

This paper presents the research work to investigate the impact of different parameters on the results of a numerical modeling for a nailed wall constructed in residual soil. Stability analysis of a soil nailed wall was carried out with Strength Reduction Method (SRM) and in the modeling stage, different conditions were considered. Element type, mesh density and excavation stages were three criteria whose effect was investigated in the current work. Finally, the result of analyses for the above-mentioned cases are to be presented and discussed in this paper in terms of Factor of Safety, wall deformation and structural forces.
