Method, device and equipment for evaluating ground settlement risk of power transmission tower and medium

Abstract

This application discloses a method, apparatus, equipment, and medium for assessing the ground subsidence risk of transmission towers, belonging to the field of power facility safety assessment technology. The method includes: acquiring ground subsidence data of the transmission tower area; extracting multi-source environmental impact factor data and using it as input features; obtaining the ground subsidence susceptibility probability value of the transmission tower through a pre-constructed dual-model weighted fusion susceptibility prediction model; determining the differential settlement of the transmission tower foundation and the angular deformation index through the settlement data; obtaining the corresponding equivalent damage severity through a pre-fitted transmission tower ground subsidence vulnerability curve and determining the corresponding vulnerability damage level of the transmission tower; further, using this as index data, querying a pre-set risk assessment matrix to determine the final ground subsidence risk level. This method can achieve accurate assessment of the ground subsidence risk of transmission towers and constructs a complete assessment framework, providing a comprehensive and systematic risk decision-making basis for power grid operation and maintenance.
