The invention belongs to the technical field of power monitoring and maintenance systems, and particularly relates to a thermal radiation error correction method for a bolt-nut-gasket structure. Comprising the following steps: parting a heat radiation element of a bolt-nut-gasket structure; obtaining a historical database; performing normalization processing on the historical sample data values; creating a feedforward neural network; training a database and verifying the database; carrying out output training; verifying the accuracy; and inputting data to be analyzed, and obtaining optimized radiation error data. According to the method, an error feedback updating mechanism can be formed based on historical data and attribute characteristics of the historical data under the condition that multiple complex radiation sources and multiple influence factors exist, a thermal radiation error result can be updated by utilizing historical error changes, synchronous updating processing can be carried out along with co
