本研究提出一种可解释的人工智能(XAI)模型,用于预测曼谷软黏土地层中打桩振动。模型基于1,018组真实打桩测量数据构建,涵盖桩尺寸、锤击特性、传感器位置及振动测量方向的变化。模型平均绝对误差(MAE)为0.276,优于传统经验方法及其他机器学习模型(如XGBoost和CatBoost)。通过SHapley Additive exPlanations(SHAP)分析,揭示输入特征与峰值质点速度(PPV)之间的复杂关系:距打桩点距离为最重要影响因素,其次为锤重和桩径。发现非线性关系与阈值效应,深化了对软黏土中振动传播机制的理解。开发了基于Web的应用程序,便于工程师实际使用。该研究推动了岩土工程领域对打桩振动预测的精度与透明度提升,有助于优化施工方案并减轻城市环境影响。模型与源代码已公开,促进研究可复现性。

原文摘要 · Abstract (English)

This study presents an explainable artificial intelligent (XAI) model for predicting pile driving vibrations in Bangkok's soft clay subsoil. A deep neural network was developed using a dataset of 1,018 real-world pile driving measurements, encompassing variations in pile dimensions, hammer characteristics, sensor locations, and vibration measurement axes. The model achieved a mean absolute error (MAE) of 0.276, outperforming traditional empirical methods and other machine learning approaches such as XGBoost and CatBoost. SHapley Additive exPlanations (SHAP) analysis was employed to interpret the model's predictions, revealing complex relationships between input features and peak particle velocity (PPV). Distance from the pile driving location emerged as the most influential factor, followed by hammer weight and pile size. Non-linear relationships and threshold effects were observed, providing new insights into vibration propagation in soft clay. A web-based application was developed to facilitate adoption by practicing engineers, bridging the gap between advanced machine learning techniques and practical engineering applications. This research contributes to the field of geotechnical engineering by offering a more accurate and nuanced approach to predicting pile driving vibrations, with implications for optimizing construction practices and mitigating environmental impacts in urban areas. The model and its source code are publicly available, promoting transparency and reproducibility in geotechnical research.
