【 摘 要 】

Potentially unstable slopes present hazards and pose risks to the traveling public, to the transportation infrastructures, to local economies, and to the environment. The main aim of this study was to evaluate the landslide hazards along Permam–Shaqlawa main road employing the landslide possibility index (LPI) proposed by Bejerman (1994; 1998). The LPI values along with the hazard category were applied to three stations along the above-mentioned main road at Korri village. The raw data for determining the LPI and hazard category were obtained from field observations and measurements. The obtained data involved the study of 10 main characteristic features encompassing geological, structural, hydrological, and geomorphologic conditions of the area under study. Further, soil samples were obtained from the study area for conducting some selected geotechnical properties for interpretation of the obtained results. With no exceptions, all road cut slopes have adverse factors that contribute to create potentially unsafe ground above the main road. The results also indicated that the possibility of failures is high at each station. The causal factors for a landslide in the study area were also presented. In addition, the remedial measures for study slope locations are suggested based on the degree of possibility of failure and field observations.
