Optimum Design for Soil Nailing to Stabilize Retaining Walls Using FLAC3D

The behavior of a reinforced soil system depends on parameters such as the structural geometry, execution steps, density and mechanical properties soil, reinforcement materials, deformation, flexural stiffness materials. A critical parameter in design soil-nailed is optimal use materials with respect to cost. It necessary find an that cost-effective within affecting nailed system. common problem excavations increase excavation depth beyond initial wall, which will require more reinforcements. In this research, we used one approach not before method placing two rows long nails placed at appropriate depth. study, comparison between safety factor, horizontal displacement, lateral pressure behind wall has been made nail placement depths using FLAC3D finite difference software reveals for efficiency approximately middle finished height. When number same lengths was considered, installation 5 or 3 reduced maximum displacement greater extent. factor achieved.
