A case study of the vulnerability of landslide-transmission tower foundation considering the influence of tower location

Based on an actual case of a high-voltage transmission tower on a slope, the vulnerability of the tower at different positions of the slope is analyzed from the perspective of landslide occurrence possibility and disaster resistance of the transmission tower. Firstly, the main influencing factors are clarified, the landslide probability evaluation model is established by AHP, the objective weight is assigned by actual survey data, and the landslide probability is calculated by fuzzy comprehensive evaluation method. Secondly, considering the relative position relationship between the pole and the landslide, the landslide risk is calculated. Finally, based on the above results, the risk coefficient is evaluated comprehensively according to the disaster resistance evaluation index and membership relationship of the tower. The calculation results of this case show that the tower is highly vulnerable, which is basically consistent with the actual damage form. The research results and ideas of this paper can provide reference for the vulnerability assessment of similar projects.
