dc.description.abstractThe design and performance of nailed walls are considerably affected by many various factors such as the complex interaction between soil-nail-facing or restrictions of the constitutive models. Conventional approaches often overlook these problems and only provide some guidance in manuals, but their coverage may be insufficient. Numerical simulations are often performed to comprehend such effects in current practice. This research utilizes advanced 3D numerical methods and calibrated constitutive models to address these key issues: (i) the influence of bearing plate and facing material on factor of safety and nail forces (ii) the prediction accuracy of Federal Highway Administration (FHWA) simplified design chart and the numerical analyses (iii) the limitations of linear and nonlinear constitutive strength models when used with strength reduction procedures. To summarize, for steep slopes the existence of bearing plate and facing material within the numerical model significantly increase the safety and axial nail forces, whereas influence the failure modes and mobilized surfaces; FHWA the simplified method overestimates the nail loads particularly on the upper half of the wall and can be considered as an upper bound design envelope; linearized equivalent strength models tends to overestimate the stability of nailed slopes for rocks with low values of geological strength index (GSI) and high values of intact rock material parameter (mi). © 2024
