Earthquake safety evaluation database construction method and system

The invention discloses an earthquake safety evaluation database construction method and system. The method comprises the following steps: firstly, enabling a plurality of pieces of seismic related data to pass through a feature extractor to obtain a plurality of region fragment data feature vectors; performing two-dimensional arrangement on the plurality of region fragment data feature vectors to form an input matrix, and then obtaining a first scale region fragment associated feature map and a second scale region fragment associated feature map through a first convolutional neural network model and a second convolutional neural network model of a two-dimensional convolution kernel; fusing the first scale region fragment association feature map and the second scale region fragment association feature map to obtain a classification feature map; and carrying out class probability offset correction on a classification feature vector obtained by unfolding the classification feature map, and then obtaining a clas
