ABSTRACT
Prediction of soil-nailed wall deformation has been of great interest to many researchers. Excavation overall stability and performance are highly affected by such deformation especially during construction as well as the exposure to external loading. Utilizing numerical models is one the common approaches to investigate the behavior of the soil-nailed walls particularly at convex corners. The focus of this study is to assess the deformation in existence of different soil nail arrangements, namely parallel and perpendicular. To this end, three-dimensional finite element models constructed with the above-mentioned arrangements are generated. The results show that the parallel arrangement enhances the control of horizontal displacements at the convex corners due to its better anchorage of the soil-nailed wall to the back soil body, while the perpendicular arrangement improves the behavior of the vertical displacements caused by its fully reinforced zone generated with overlapping nails.
