In some regions with hot and dry climate conditions, the temperature varies greatly between day and night. Therefore, the materials used in construction projects are exposed to a large number of thermal cycles daily. In this research, the application

Abstract This research suggests a robust integration of artificial neural networks (ANN) for predicting swell pressure and the unconfined compression strength of expansive soils (P s UCS-ES). Four novel ANN-based models, namely ANN-PSO (i.e., particl

Geotechnical engineering data are usually small-sample and high-dimensional, which brings a lot of challenges in predictive modeling. This paper uses a typical high-dimensional and small-sample swell pressure (Ps) dataset to explore the possibility o

Expansive soils cover a huge portion of the total land area in the world. They absorb water and expand, then shrink when they dry out. The volume change exerts pressure on engineering structures causing deformations, cracks, and movement of walls. Th
