Description
Tong Zhao and colleagues tested landslide pile monitoring in 2025 with a lab model. Concrete piles hold back sliding loess slopes in landslide zones. Warning signs before a pile fails are hard to spot. The team built a model box of a loess slope and pile. Repeated graded loading mimicked natural sliding pressure. Tiny sound signals from the concrete were recorded throughout. Those acoustic signals were matched against pile bending.
Sound counts and energy stayed flat, then jumped suddenly. Signal tone and strength passed through four clear stages. Early damage sounded low and quiet. Stable growth sounded high but still quiet. Fast damage growth shifted tone and raised strength. Failure arrived with low tone and high strength. A rising share of low-tone energy marked danger best. It flagged the slide into fast, unstable movement. The authors offer sound monitoring as a live warning tool.
