碩士 === 國立中興大學 === 水土保持學系所 === 103 === Hattori (2009) found that the self-potential variation is earlier and more significant than pore water pressure before soil sliding beginning. This research is helpful for warning system of landslide hazard if we used it on monitoring of landslide hazard. This study is to explore the self-potential variations and acceleration signal at the sliding condition by loading. We use the iron plates loading on physical model slopes and embed the non-polarizing electrodes and accelerations. The conclusions are self-potential variations, characteristics of seismic signal and frequency range of seismic signal after the sliding occurring.
