In response to transmission tower tilting accidents caused by uneven ground settlement induced by goaf areas

this paper analyzes existing treatment methods for correcting inclined transmission towers and studies a new elastic correction technology for transmission tower inclination. A jacking correction device is designed

and its mechanical properties are analyzed using finite element calculation. The correction technology is then applied to a 750 kV transmission tower in a goaf area of Ningxia. The on-site application results show that the maximum bearing capacity of the 490 kN jacking correction device meets the requirements for correcting the inclination of 750 kV transmission towers. The research results can provide a methodological reference for similar engineering projects.
