Aiming at the problem that the traditional seismic evaluation of buildings time-consuming and the difficulty in a large-scale implementation,this paper proposes a seismic capacity evaluation model for buildings based on U-Net++.The model takes U-Net++as the backbone network,integrates multiple information sources,such as high-resolution remote sensing images,building construction age,height,use and structural types.Tak-ing the Yucheng District of Ya'an City,Sichuan Province,as the study area,17 compara-tive experiments were designed to explore the degree of influence that different features have on the seismic resilience of buildings.This work provides robust technical support for refined assessments of earthquake disaster risks on a broad scale.
