摘要

Convenient methods for predicting the peeling and of cover concrete falling off based onrnreinforcement corrosion amount require a lot of inspection data, and assume the correction based onrnseveral inspections because there are many uncertainties. In this study, the authors propose arnmethodology using inhomogeneous Poisson process for estimating the peeling and falling processrnbased on a small amount of inspection data. In addition, the proposed model was applied to the datarnon the inspection of the railings of RC railway viaducts, which would undergo the compositerndeterioration due to neutralization and salt damage, and it was found that the proposed modelrnenables the prediction that takes into account the increase in reinforcement corrosion rate andrnexplains the process of peeling and falling more accurately than a homogeneous Poisson model.
