AI-based real-time multi-model framework for groundwater-responsive pile behaviour
Piles react nonlinearly and time-dependently to fast groundwater level fluctuations due to pore pressure and effective stress changes. Traditional design models use static stress assumptions and cannot update soil-structure interactions in real time, limiting their hydrologically active prediction power. This research presents an integrated multi-model framework with sensor networks, adaptive soil-mechanics formulations, machine-learning-based modulus development, probabilistic failure evaluation, and actuator-driven stiffness control. The framework includes a real-time groundwater-Terzaghi interaction model for dynamic effective stress evaluation, a transformer-network architecture for evolving soil modulus prediction, a Bayesian load-redistribution model for failure probability estimation, and a self-actuated response optimizer for localized stiffness corrections. Hydro-mechanical conditions are updated continuously via closed-loop elements. The integrated system outperforms earlier methods in settlement prediction, directional stress estimation, modulus evolution tracking, and risk-aware load control using full-scale pile testing datasets & samples. Pile foundations subjected to different groundwater regimes improved in accuracy and reliability, enabling intelligent, self-regulating geotechnical infrastructure sets.
Executive Impact
This research introduces an AI-based multi-model framework for real-time analysis and control of pile behavior influenced by fluctuating groundwater. It integrates sensor data, adaptive soil mechanics, machine learning, and probabilistic methods. The framework continuously updates effective stress, predicts soil modulus evolution, estimates failure probabilities, and adjusts pile stiffness proactively. Tested against full-scale datasets, it significantly improves accuracy in settlement prediction, stress estimation, modulus tracking, and risk-aware load control compared to traditional and standalone ML methods. This intelligent system enhances reliability and enables self-regulating geotechnical infrastructure.

Methodology: The proposed framework integrates five core models: RAGTI-M for dynamic effective stress, DASTM for anisotropic stress tracking, ESMT-Net for modulus prediction, BRILR-M for failure probability, and SAPRO for stiffness optimization. It leverages real-time sensor data, deep learning, and probabilistic simulations in a closed-loop system.
Experimental Setup: Large-scale testing facility (6m x 6m x 10m) with reconstituted silty sands and clay. Sensors include piezometers, fiber-optic strain gauges, and DGIS probes. Groundwater levels manipulated in sinusoidal cycles (60% to full saturation, 1.5 kPa/hour fluctuation). Datasets include 2,000 historical pile load tests and 15,000 synthetic hydro-mechanical scenarios.
Results & Validation: The integrated framework achieved a R² settlement prediction accuracy of 0.928 (MAE 3.2mm), MASE stress tracking of 7.4 kPa, relative modulus error of 6.2%, and failure detection accuracy of 93.6%. These metrics significantly outperform benchmark methods, demonstrating superior accuracy and reliability under dynamic groundwater conditions.
