Influence of transmission tower load under extreme conditions during operation period on the stability of landslide and tower foundation
View through CrossRef
Abstract
Taking Yanzi landslide and 500 kV transmission tower foundations on the landslide as the research object, this paper presents a study of the influence of transmission tower on the stability of landslide and tower foundation under extreme conditions during operation period. Firstly, the ultimate loads of transmission tower foundation under different operating conditions are determined. Secondly, based on the limit load of transmission tower, the overall and local stability of Yanzi landslide is analyzed. Finally, the disturbance of tower foundation load state on soil around the tower foundation and the change of tower foundation displacement are studied. The results show that, with the increase of wind speed, the tower foundation load In addition, under the action of wind load, the soil around the adjacent tower foundation basically does not affect each other, the maximum displacement of tower foundation does not exceed 0.5 mm, and the maximum inclination rate of tower foundation meets the requirements of cod.
