Three-Dimensional Finite Element Analysis of Soil-Nailed Walls: Effects of Wall Configuration and Soil Properties
Soil nailing has been widely used as a soil reinforcement technique to retain slopes and walls. In this study, a three-dimensional (3D) finite element (FE) model was developed to simulate the performance of an instrumented full scale soil-nailed wall reported by the French national research project CLOUTERRE. The 3D-FE model better simulated the behavior of the soil-nailed wall compared to two-dimensional (2D) FE models reported in the literature. The 3D-FE model was used to investigate the effects of wall and nail inclinations, nail horizontal spacing, and retained soil properties on the wall performance. The global factor of safety was considerably affected by the nail horizontal spacing and soil friction angle. The top horizontal displacement of the wall was significantly affected by the wall and nail inclinations, soil friction angle, and soil modulus of elasticity. Furthermore, the maximum tensile forces in nails were highly influenced by the wall inclination, horizontal spacing between nails, and soil friction angle.
