Published on March 30, 2026 by Cheng-Yu Ku
Executive Impact: Revolutionizing Geotechnical Design
This study proposes an AI-enhanced framework for CPT-based soil behavior classification, specifically addressing challenges with incomplete CPT data in offshore wind farm projects. Utilizing a comprehensive synthetic CPT database, the random forest model achieved superior performance (R2=0.99, accuracy=92.53%) compared to ANN, SVR, and DT. The framework demonstrates robust classification even with missing data, identifying cone tip resistance, sleeve friction, and effective stress as dominant factors. Monte Carlo simulations confirm reliability within a 95% confidence interval, offering a practical solution for geotechnical design in offshore wind farms.

Robertson Classification
The Robertson Classification framework is a widely adopted empirical method for interpreting soil behavior from CPT data. It characterizes soils based on measurements like pore water pressure, sleeve friction, and cone tip resistance, providing a behavior-based interpretation crucial for site characterization in heterogeneous deposits. The classification uses normalized parameters to reduce overburden stress influence, with a contour-based representation for refined interpretation.
AI-Enhanced Models
This study leveraged various machine learning models including Random Forest (RF), Artificial Neural Network (ANN), Support Vector Regression (SVR), and Decision Tree (DT) to enhance CPT-based soil classification. RF consistently outperformed others, demonstrating superior capability in handling complex, nonlinear relationships inherent in CPT data, with an R² of 0.99 and a classification accuracy of 92.53%.
Missing Data Robustness
A key focus was evaluating model robustness under incomplete CPT data. Simulations showed that reliable predictions could be maintained even when certain parameters were missing. While the absence of critical parameters like cone tip resistance (q) or sleeve friction (f) significantly reduced accuracy (to 58.74% and 55.31%, respectively), the model generally proved robust.
