Finite Element Modeling of the Soil-Nailing Process in Nailed-Soil Slopes

The finite element technique has been accepted as a tool for modeling geotechnical complex processes. In this study, (FE) of various stages the soil-nailing process, i.e., construction and overburden pressure stages, is carried out considering different soil parameters, simulating with in-house developed laboratory models. process built in models idealized plain strain problem modeled PLAXIS software. consist Perspex sheet box containing sandy slope, facing, steel bars reinforcement plate foundation. stress–strain relationship sand represented by Hardening-Soil model. interface at nail described Coulomb friction behavior during stage under varying density, are investigated terms displacements slope stress conditions mass. mass all well presented FE compared model test data. sensitivity analysis models’ dimensions three-dimensional nailed-soil slope. It can be concluded that potential to simulate performance field working could provide guidance construction/maintenance soil-nailed cut slopes granular soils/weathered rocks.
