AI-POWERED GEOTECHNICAL ANALYSIS
Comparative Performance Evaluation of Machine Learning Models for Predicting the Ultimate Bearing Capacity of Shallow Foundations on Granular Soils
Leveraging cutting-edge Machine Learning to enhance the accuracy and efficiency of critical infrastructure design.
Executive Impact & Key Findings
This study demonstrates how advanced ML models can revolutionize geotechnical engineering, providing actionable insights for enterprise decision-makers.
This study comprehensively evaluates six machine learning (ML) models—k-Nearest Neighbors (kNN), Artificial Neural Network (NN), Random Forest (RF), Extreme Gradient Boosting (xGBoost), Adaptive Boosting (AdaBoost), and Stochastic Gradient Descent (SGD)—for predicting the ultimate bearing capacity (UBC) of shallow foundations on granular soils. Utilizing a dataset of 169 experimental results, the models were assessed using multiple metrics including R², MAE, MAPE, RMSE, MSE, and an objective function. AdaBoost consistently outperformed other models, achieving the highest R² values of 0.939 (training) and 0.881 (testing). The research also employed SHapley Additive Explanations (SHAP) and Partial Dependence Plots (PDPs) for enhanced model interpretability, revealing that foundation depth (D) and angle of internal friction (φ) are the most influential parameters. While promising, the study notes the limitation of using single-layer soil data and recommends future work with multilayer datasets to improve generalizability.

Ultimate Bearing Capacity (UBC)
The maximum stress a foundation can sustain before shear failure. Accurate prediction is vital for structural safety and economical design, often involving complex soil-structure interaction. ML models provide a data-driven approach to bypass traditional simplifying assumptions.
Machine Learning (ML) Models
Algorithms like AdaBoost, kNN, RF, xGBoost, NN, and SGD used for pattern recognition and prediction. Their application in geotechnical engineering offers efficiency and reliability by learning from experimental data, overcoming limitations of traditional analytical methods.
Model Interpretability (SHAP & PDP)
Techniques to understand how ML models make decisions and the influence of input features. SHAP quantifies individual feature contributions, while PDP illustrates marginal effects, enhancing trust and enabling domain experts to validate model behavior.
Foundation Geometry & Soil Properties
Key input parameters including foundation width (B), depth (D), length-to-width ratio (L/B), soil unit weight (γ), and angle of internal friction (φ). These factors significantly influence UBC, and their accurate representation in ML models is crucial for reliable predictions.
