State‐of‐the‐Art Review of Vibration‐Based Health Monitoring of Piles
Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Vibration‐based health monitoring (VHM) has emerged as a promising technique for assessing the integrity of deep foundations by interpreting variations in dynamic response governed by soil–pile interaction. This review presents the theoretical background of foundation failure mechanisms, sensing technologies, and numerical approaches that underpin VHM ...
