Development of Rockfall-Monitoring System

Taiwan is an area with highly geological fragility. Recently, due to the impact of extremerainfall, fallen rocks become more and more common along the slopes of the road banks through themountains. Fallen rocks interrupted the roads and could seriously endanger the safety of the passers.According to the literature abnormal electrical signals, with the frequencies mainly between 1 Hz to0.01 Hz, precede the breakdowns of the rocks. Objective of this project is aimed at developing anew generation of geoelectrical-data-based monitoring system, attempting to detect the electricallyanomalous signals inside the rocks, on the rock-falling events, particularly for the road banks in themountains. The system, as an early warning signal, can ultimately combine the blocking action onthe road, closely cooperating with the competent authorities, to protect the safety for the public.
