Abstract: The development of electric power enterprises is of great significance to the national economic level. With the technical support in recent years, good economic benefits have been obtained. It plays an important role in the development of modern society. Transmission line tower foundation design is a key work in power enterprises. It directly affects the function of the power system. Based on this, starting from the importance of transmission line tower design, and starting from the engineering practice, the problems faced by the transmission line tower foundation are analyzed as follows: the geological environment is complex, affected by wind load, and the design scheme has defects. In this paper, the optimal design strategy and precautions of transmission line tower foundation are proposed for reference.
