Abstract:
This research has studied and investigated some landslides that caused many transportation problems in the region of Bandben-Laie Road in Neka situated in northern Iran. Given the large number of landslides in this path and the high cost of stabilization, first the task of the identification of a new path with a higher safety factor was undertaken. In order to do so, some effective factors in slop instabilities were studied and investigated in this region. In addition, the geographical positions of the previous landslides in and around this path were recorded by GPS. Finally, a digital and raster layers of the effective factors in the landslides of this region using the geographic information system (GIS) was provided. Furthermore, the landslide hazard zonation map was outlined using the density area method in the concerned range subsequent to conducting necessary analyses and computations on the information layers. Using the information obtained from this particular zonation map as well as the desert examinations, the most suitable path was eventually identified and thus proposed
