Predicting Soil Bearing Capacity with Advanced AI for Infrastructure Design
The California Bearing Ratio (CBR) is a crucial geotechnical indicator, but traditional lab tests are time-consuming and costly. This study introduces a comprehensive machine learning framework, analyzing 382 soil samples from Türkiye. By leveraging 12 ML algorithms, we demonstrate how AI can accelerate and enhance precision in infrastructure planning, offering a powerful alternative to conventional methods and driving digital transformation in civil engineering.
