The invention discloses an engineering safety evaluation method based on score difference Stacking multi-model integrated learning. The engineering safety evaluation method comprises two stages of structural body feature extraction based on an attention mechanism and model integration based on score difference. The idea of a divide-and-conquer method is adopted to divide the whole dam into a plurality of local areas (single domains). Based on the result of structural body region division and each single-domain operation state evaluation, a structural body global comprehensive evaluation modelis adopted, a single-domain evaluation result data set is used as the input of the model, and attention weights are dynamically distributed to different single domains by utilizing an automatic encoder based on an attention mechanism; the Stacking method based on the score difference is used for integrating various judgment models, and accurate and stable safety comprehensive judgment is carried out on the overall situation of the structure body.
