Abstract

Overhead distribution poles are widely distributed with large quantity. However, the poles are prone to overturning under extreme weather conditions, which threaten the power supply of local areas or even the entire distribution line. How to apply scientific and effective methods to simulate and analyze the anti‑overturning ability of poles has now become a key technical issue in the construction and transformation of distribution networks. To address the problem, this paper takes 10 kV reinforced concrete poles as an example, the load and internal force considering meteorological conditions are calculated first. Then, based on the FLAC3D software, a simulation modeling and analysis method for the anti‑overturning ability of distribution poles is proposed. Finally, a calculation analysis of example is carried out in combination with soil parameters in a certain area of Henan. The deformation damage process of the foundation under extreme weather conditions is analyzed in detail and the load‑displacement curve is drawn. The contribution of this research can provide technical support for the installation and reinforcement of distribution poles.
