Abstract :
Slope instability is regarded as a worldwide problem that has direct effect on human life and the environment. The human intervention in nature by building structures and disrupting natural causes increase in the number of landslide event. Landslide hazard zonation mapping is considered to be one of the most reliable methods for evaluating the potential of landslide event along road. These maps can provide in the way of useful information in relation to the identification of high risk areas offer and accordingly, stabilization methods proposed to prevent such risks. In this study, maps of hazard zone landsliding were produced, by using fuzzy logic in ArcGIS and IDRISI along Kan–Suleghan road. Then, in order to assess the accuracy and efficiency of different operators, for creating better results, the fuzzy method was used. Based on studies, revealed the effects of tectonic factors such as faults is most effective parameter. In zoning maps, risk of landslide with fuzzyoverlayOR, the scope of present landslides in the region compared to the area with possibility of landslide occurance in the maps have been showed the good matching. So, in the paper, area it is suggested to prevent construction projects in area with high probability of landslides.
