Physics-Informed and Explainable Machine Learning for Expansive Soil Swell–Shrink Dynamics: A Critical Review of Computational Architectures, Constraints, and Validation Paradigms in Geotechnical AI
Expansive soil prediction involves more than estimating a swelling index from classification properties. Engineering decisions depend on path-dependent deformation, evolving water retention, restraint, fabric change and uncertain environmental forcing. Physics-informed and explainable machine learning offer complementa...
