In current landslide investigation, two dimensional modeling is used to estimate three dimensional movement of landslide. Since three dimensional movement of landslide take place in a complicated manner, it is necessary to consider the three dimensional nature of landslide to do slope stability analysis and construction. In this paper, 1. Geological features more detailed, three dimensional structural information is obtained. 2. Water path can be presumed in three dimensions, and more economical ground water drainage works be planned. 3. There is possibility that the effect of construction of ground water drainage works can be quantitatively understood. were shown by using geophysical exploration in addition to a past investigation technique.
