Abstract

Landslides are natural hazards that are commonly observed in nature. They generally cause loss of life and property, because they can severely damage engineering structures such as dams, highways, railways, pipelines, and buildings. The potential zones of landslides need to be specified and their failure mechanisms need to be understood to mitigate the effects of landslides on societies, economies, and industries. Therefore, potential landslide zones need attention, specifically for engineering structures with large investment values. The identification of zones with a high potential risk of the occurrence of landslides is essential to avoid possible losses due to landslides. An analysis of the landslide susceptibility of potential areas results in the safer application and performance of engineering projects, and it helps engineers to take important measures regarding potential landslide damage. In this paper, a landslide failure that occurred during the construction of the transmission line of the Kars Dam is presented and possible measurements to avoid landslide damage on the transmission line are investigated. Slope-stability analyses were performed using the limit-equilibrium method, and as a result of the analysis, two different engineering solutions are proposed to avoid landslide movements. A cost analysis for the proposed solutions is also made to specify the optimum solution by considering both safety and costs
