摘要: 
本研究建立一室內大型邊坡模型,可依試驗設計需求調整試體性質、大小等,且能使用不同的外力因素,如模擬地下水滲流、人工降雨與邊坡上加載重等方式對邊坡模型進行破壞,並且可在破壞過程中量測各物理量。
本文主旨為以模擬地下水位上昇之方式使邊坡模形試體產生管湧破壞,在破壞過程中量測電位差訊號與振動訊號。歸納試驗結果後發現,當邊坡試體因管湧破壞而崩塌會使電位差產生驟減,並可同時對應振動訊號。試驗開始時,電位差會隨土壤水份含量增加而上昇到一最大極值,且在邊坡試體發生崩塌前100~200秒不等時電位差會從最大極值開始減少,直到產生邊坡崩塌。此現象的發現,或可具有潛力可作為崩塌的前兆預警訊號之一。

The experiment was set up an indoor equipment for model slope testing. According to the soil, and so on, it can be well-adjusted and assorts different external forces to break the model slopes such as simulating groundwater seepage, article rainfall, and increase of load on the slope. It would measure each physical data in the process.
The intention is to cause the failure by piping on the model slope by the simulation of groundwater rise, and then record the electrical potential and vibrational signals with it. Consequently, we found that as the model slope collapsed, the failure by piping made the decrease of electrical potential difference and it would correspond to the vibrational signals.
When the test starts, the electrical potential difference will go up to extreme value owing to the rising of moisture contain. And then, the electrical potential difference begins decreasing 100~200 seconds until the model slope collapses. The discovery may be a warning before slope collapsing.
