赤外線サーモグラフィー法の検証結果と新たな点検手法の一考察

抄録

It has been pointed out until now that diagnosis of the concrete structure by the infrared thermography method has a high possibility of incorrect-detecting reflection and thermal radiation, and that judgment of the time suitable for investigation cannot be checked spot. Furthermore, even if it judges it as the unusual part by the infrared thermography method, the damage situation of the unusual part cannot be guessed. To solve such a problem, by this research, a damage situation can be guessed to some extent by performing heat conduction analysis and the scope of an infrared camera was checked by conducting an indoor experiment. In the main issue, the new check technique is proposed based on these research results. While this technique can judge objective time suitable for investigation, it becomes possible to guess a damage situation in a certain amount of accuracy.
