This study is to propose a more reasonable durability prediction models about compression strength and carbonation of Seoul Metro. The Seoul Metro has been used more than 30 years and accumulated many diagnosis data for about fifteen years. As a result of the analysis of compressive strength and carbonation, we were able to draw prediction models with accuracy of more than 80% and confirmed the prediction model's reliability by comparing it with the existing models. We've also confirmed field suitability of the prediction models by applying field, the average error of an estimate on compressive strength and carbonation depth was about 20%, which showed an accuracy of more than 80%.
