Bridge Anomaly Diagnosis Based on a Feature-Augmented BiLSTM Autoencoder and Hotelling T2 Test

For bridges in long-term operation, only limited abnormal samples with clear labels are available, which makes it difficult to apply conventional supervised methods that require sufficient labeled data. To address this problem, this study proposes a bridge anomaly diagnosis metho...

A Distributed-Acoustic-Sensing-Based Method for Early Warning of Urban Road Subsurface Cavities Using Vehicle-Induced Vibrations

Rapid underground development in cities increases the hidden risks of roadbed cavities. Traditional geophysical methods, such as ground-penetrating radar (GPR), are costly and unsuitable for automated large-scale monitoring. This paper proposes a distributed-acoustic-sensing (DAS...
