埋設鋼構造物のカソード防食を対象とした数値解析に関する一考察

抄録

It was verified by two experiments that the potential in soil satisfied the Laplace equation, which is usually assumed in numerical analysis methods for the catholic protection of buried steel structures. In the first experiment, where the current distribution was uniform, it was found that the relationship between the potential and the distance was linear. In the second experiment, where the current distribution was complicated, it was found that the experimental results agreed well with the calculated results based on the Laplace equation. The polarization curve for steel in soil was also measured and its characteristics were discussed from the viewpoint of use in the numerical analysis.
