Assessment of Geotechnical Properties of Fine-Grained Soil Using AI Techniques

Abstract

The variables determining the engineering qualities of fine-grained soils include the consistency limits, which are classified as primary features, and the water content, density, and soil structure, which are classified as secondary properties. The Specific Surface Area (SSA), clay percentage of clays, and Liquidity Index (LI) were found to be sporadically correlated with the plasticity ratio of clays (Rp), which is defined as the ratio of plastic limit to liquid limit. This study examines over a thousand data points from scientific studies and literature. Rp was also used to understand the Casagrande plasticity chart. While there is a less noticeable association with the clay proportion, Rp drops as "modified" SSA increases. The LI and Rp have a range of 0.2 to 0.8. According to the results, the physical characteristics of clays are consequently quite changeable, and it isn't easy to establish a unique relationship between the properties. This study aims to provide a broad overview of the interrelationships between clays' technical features.
