Unstable Slope Monitoring and Early Warning by Multi-point Tilting Sensor and Pipe Strain Gauge

Conference paper
Part of the Lecture Notes in Civil Engineering book series (LNCE, volume 62)


Real-time monitoring is essential for avoiding potential damage that may be caused by the failure of a marginally stable slope. This study investigated an unstable slope monitoring system that was comprised of a multi-point tilting sensor, including a pipe strain gauge. The monitoring process utilized additional supporting devices (e.g. water level gauge and rain gauge) that were installed on a cut slope site. Movement data was transmitted by way of a wireless communication system. The wireless system detected movements within the slope and that were generated by heavy rains. Analysis of the recorded data revealed that the rate of movement, or tilting, was influenced by the groundwater fluctuation and antecedent rainfall. Considering the tilting rate, three levels were identified as warning indicators and thus a time prediction formula was proposed. It could be suggested that this monitoring technique would be applicable for an early warning in the event of a rainfall – induced slope instability.
