Abstract: The construction of ultra-high voltage overhead transmission lines has progressed quickly in recent years,and the project’s main focuses are the choice of line channels and the stability of tower foundations. The influence of geological disasters like collapses, landslides, and mudslides on the safety of the route can be significantly reduced by selecting a stretch with favorable geological conditions as the route passage. However, as engineering development advances, power grid density rises and the issues associated with geological disasters become more complicated and unpredictable. Ancient landslides are one of the geological risks that are well concealed, hard to spot, and vulnerable to perturbations. Due to their lengthy history and lack of distinctive topographic characteristics, current landslides are difficult for humans to identify, which has resulted in a lack of awareness of this problem during the first phases of choosing a construction site. Additionally, because to their susceptibility to perturbations, ancient landslides are particularly vulnerable to unstable sliding, which not only hinders technical building but also results in significant financial losses and even fatalities. Therefore, a crucial study area in the present engineering building process is how to recognize historical landslides and adopt appropriate avoidance measures.
