Abstract

Damages of road embankments caused by earthquakes and heavy rains have often reported in Japan. It is therefore important to evaluate stability of road embankments. But huge numbers of roads were already constructed, and information of old minor roads is not recorded in details. It needs cost and time to prepare information for the evaluation of embankments. To overcome this problem, this study tried to make a model which can extract embankment on mountain roads using high accuracy DEM. Existing real road section was selected, and accuracy of the models with different condition are confirmed based on logistic regression analysis. In order to screen the embankments based on the results, it was confirmed that very high extraction accuracy was obtained from the model by excluding retaining walls and reinforced soil walls.
