Evaluation of landslide stability of pole tower foundation based on analytic hierarchy process

At present, most of my country's 110kV transmission line planning passes through mountainous areas, and the threat of landslides to transmission towers cannot be ignored. This article describes the typical characteristics of landslides, and extracts the causes of landslides based on them. Based on the analytic hierarchy process, the weight of each cause to the formation of the landslide is studied, and the stability evaluation model of the tower foundation landslide is constructed based on this. Through the analysis of the results, the principle of site selection for the foundation of transmission poles can be put forward.
