Research on Compressive Performance of Prefabricated Foundation for Transmission Lines

Transmission lines are a key link and important component of the national power transportation system. Although prefabricated foundation structures have been widely used in civil engineering construction, they have not yet formed a unified transmission line standard. Therefore, this article adopts numerical calculation analysis methods to conduct systematic numerical calculation analysis and research on the compressive performance of prefabricated foundation structures for transmission lines. The main research conclusions are as follows: (1) Compared to other bottom modules, the central column module can adopt a larger size, making the cross-section that bears tension larger, mthereby reducing the numerical value of tensile stress in the central column concrete. (2) Contact stress: Contact stress mainly develops from the bottom and gradually decreases from the maximum value at the bottom. The contact stress of the foundation above the compressive load decreases.
