Abstract

This chapter delves into the parametric optimization of design factors for driven soil nail structures using the finite element method framework. It begins with an introduction to soil nailing, its historical background, and its applications in various regions, including Nepal. The study compares driven soil nailing with traditional grouted methods, highlighting the advantages and disadvantages of each. The modeling process is conducted using PLAXIS 2D, with a focus on the Mohr–Coulomb model for analysis. Key parameters such as Young’s modulus, Poisson’s ratio, cohesion, friction angle, and dilatancy angle are determined for the analysis. The study also explores the use of Python scripting to automate the modeling process, significantly reducing the time and effort required for extensive simulations. A sensitivity analysis is performed to distinguish between weaker and stronger soil nailing models without running all simulations. The chapter concludes with a discussion on the factors influencing the behavior and performance of soil nail walls, providing valuable insights for professionals in the field.
