| Research Abstract |
We focused on the location of water path to predict the failure location in mountainous slope. In this study, we discussed about the heterogeneity of weathering for soils and bed rocks in the slope failure and non slope failure location.
The results were followings ; 1. Groundwater levels moved up around the water path locations. Apart from water paths, the groundwater level did not occur. 2. Soils and bed rocks were weathered around the water path locations. Apart from water paths, soils and bed rocks did not weathered. 3. Slope failure occurred under the conditions that soils and bed rocks were weathered and groundwater levels moved up.
