This study on observe with application of groundwater logging of landslide. If the depth of potential landslide can be measured by groundwater logging, it can control latent landslide layer depth. The results were summ arized as follows:
1. Composited of geological structure, strain value of layer and groundwater logging data analysis. Flowing layers of groundwater are situated at place that is connected with broken zone of surface and layers, so flowing layer discharge increase, then it induces landslide .
2. Compared flowing layer with resistant value, the change rate increase by pump water logging. The maximum change of specific resistance at flowing layer accuracy near water surface.
3. Pump water logging produces vertical flow effect, it's better than general logging effect and easy to know where is flowing layer.

1. 綜合地質構造與地層應變量及地下水檢層資料之分析得知,地下水之流動層大部分位於表土層破碎帶及層理交接處,而地層滑動面亦位於破碎帶及層理交接處,因此,地下水流動層之流量增大時,將會引起地層之滑動。
2. 抽水檢層法能使流動層之比電阻值變化幅度增大,而愈接近水面之比電阻值的變化則愈大。對於地下水位之上的地下水的流動狀況時,食鹽水的檢層法無法檢測其流動層。
3. 抽水檢層法由於經抽水所產生之垂直流作用,其檢層的效果比其他之檢層試驗更能準確地研判其流動層,因此,抽水檢層法有效於地下水之檢層。
