Abstract

This research presents the characteristics of soil stability and rupture in forest road of Sbilarg forest ecosystem. Three segments of road
including landslide, consolidated and control areas were selected for stability analysis. Six samples were collected from each area and the Plastic
Limit (PL), Liquid Limit (LL), Shrinkage Limit (SL) and their indices as well as soil moisture, texture and direct shear were determined at soil
mechanics laboratory. Results indicated that the soil texture in both areas was sandy clay. According to direct shear test for landslide area, the safety
factor against mass movement was less than 1 which indicates that this area is unstable. For consolidated area the safety factor was equal to 1 which
indicates that this area is stable
