英文摘要	Abstract With the construction of “West-to-East Power Transmission” and national networked engineering projects, high-voltage transmission towers, which are important components of transmission lines, are important power engineering facilities. They are inevitably erected on the ridges, edges of steep slopes, and river banks. Therefore, induced by internal factors and external factors, it is easy to cause landslide disasters in these areas, resulting in power grid accidents such as tilting of power poles, disconnections, and trips. This article takes the Yanzi landslide in Badong County and 500kV transmission tower on the landslide as the research object. For the combined foundation excavation form of the tower foundation, the relative positions of different tower foundations and landslides and the loading of spoil are analyzed. The influence of excavation of transmission tower foundation and pile dumping on the stability of the landslide is discussed. The research results show that the effect of the combined foundation excavation on the stability of the landslide is negligible, but it will affect the stability of the local landslide, and the stability of the local landslide is related to the relative position of the tower foundation and the landslide. In addition, the pile loading of spoil will also affect the stability of local landslides, and the degree of impact is related to the size of the spoil pile.
