Outline of Final Research Achievements

As development of the frost damage depth evaluation, amount of scaling damage of the concrete surface portion was improved by a visual evaluation system. Surface irregularity figure was grasped with the non-contact digital photography of the frost damage deterioration part. In addition, both infrared ray's thermography method and the ultrasound method are necessary. And then a three-dimensional model was command in the considered technology of the frost damage depth by the unification of the each method result. Because a hierarchical neural network is used, in the frost damage under natural environments of the compound deterioration, that damage inference and evaluation is possible. In this research, each subject matter of concrete frost damage depth is basically needed as three dimensions model of deterioration predictive inference.
