N2  -  Communication networks and roads are important part of the investments of each country. Beside of this, maintenance  of these large communication networks and process of developing construction are among the causes of the degradation of natural resources. In this research , occurrence of landslides in Kiasar road, located in the south of Sari city, was evaluated by using basic physical model, SHALSTAB, and slope stability map of this area was determined by this model. First, the physical and mechanical properties of 15 soil sample near the main roadside were measured and compared with 115 cases of landslides around the road. Results of Square research, analysis of geological data, and laboratory tests showed that for all landslides occurrence, 43.49 percent of actual landslides have been located in unstable regions. Then, the roadsides have been distinguish from happened landslides, in natural conditions. Then a separated model has been run for each landslide. The results showed that whenever SHALSTAB model has been implemented by using roadside landslides, this model can simulated only 18.55% of slip points in unstable zones, and when SHALSTAB model implemented by using slips which occurred in natural conditions , by predicting 69.5 percent , is a successful usage.
