Abstract：In order to promote the promotion and application of smart concrete in the field of engineer-ing monitoring,this article introduces electrical resistance tomography(ERT)into the monitoring of smart concrete structures.The conductivity and sensitivity of smart concrete were studied through ex-periments,and the changes in boundary voltage signals of smart concrete under pressure and with cracks were analyzed through finite element simulation.The research results indicate that there is a good correspondence between the change in resistance value of smart concrete and its load situation before its failure.The force information and crack information can be feedback through boundary volt-age signals.In addition,a resistance tomography inversion imaging algorithm program was developed in the article,which obtained the resistance grayscale image of the uneven stress inside the cylindrical structure,laying the foundation for its promotion and application in engineering monitoring.
