Development and Validation of a Seismic Design Method for Anchored Retaining Walls
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Engineering Characterization of Subgrade Soils of Jimma Town, Ethiopia, for Roadway Design
Geosciences, 2020 Soils are naturally occurring materials that carry loads of civil engineering structures including roads and buildings. However, not all natural soils are suitable for such uses due to limited strength and instability under varying environmental ...

Applied Research, Volume 5, Issue 5, October 2026.This study introduces a reliability‐calibrated machine learning framework to predict the maximum dry density and optimum moisture content of heterogeneous soils. By integrating 15 algorithms with conformal prediction, the models deliver accurate compaction estimates alongside rigorous, distribution‐free 90% confidence intervals.

Effect of the Field-Stress State on the Subgrade Resilient Modulus for Pavement Rutting and IRI
Geotechnics, 2023 The new Mechanistic-Empirical Pavement Design Guide (MEPDG) uses the subgrade resilient modulus (MR) as the key input parameter to represent the subgrade soil behavior for pavement design.

Applied Research, Volume 5, Issue 5, October 2026.This review highlights how pretreatment and optimized mixture design enable the use of phosphogypsum in pavement base courses and subgrades. Combining physical, chemical, or thermal treatment with suitable binders and solid wastes can improve engineering performance, durability, and environmental safety.

Engineering Reports, Volume 8, Issue 9, September 2026.This study investigates time‐dependent settlement of pile foundations. A hybrid framework combining Artificial Neural Networks and Finite Element Modeling was developed to derive an empirical equation for the pile‐soil system stiffness evolution over time. The model was validated and calibrated using laboratory test data.
