Hattori (2009)發現土體開始滑動前,自然電位變化較孔隙水壓變化來的早且顯著。若將此現象善用於山坡地災害之監測,對山坡地災害預警系統有所幫助。本研究為探討邊坡滑動之自然電位變化及加速度訊號,埋設非極化電極與加速度規,以鐵板加載方式觀察邊坡物理模型在受外力加載下,自然電位變化情形及發生滑動時加速度訊號特性。本研究總結出滑動發生時之自然電位變化情況、振動訊號特性及頻率範圍等。

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.
