Deterministic design optimization for soil nail walls in a Brazilian highway construction

Soil nail walls are widely used for slope stabilization in transportation infrastructure; however, their design still relies predominantly on manual, trial-and-error procedures or simplified Limit Equilibrium Method (LEM) analyses, which do not ensure optimality. Existing optimization studies are typically limited to i...

Three-dimensional evaluation of EPS geofoam elastic parameter sets and vehicle load configurations using large-scale field tests

This article presents numerical modeling results using the Finite Element Method (FEM) of a large-scale experimental embankment built with Expanded Polystyrene (EPS) blocks over a soft soil subgrade. The study addresses technical gaps and economic implications, as EPS design parameters derived from small-scale laborato...

Deterministic, Reliability-Based and Risk-Based Design Optimization of Earth Slopes Using ANN-Based Surrogate Modeling

Expanding road and railway networks in developing countries is essential for economic growth and reducing regional disparities. However, such projects often face significant geotechnical stability and risk management challenges. This study presents a three-phase optimization framework consisting of: (1) deterministic,...
