Abstract

A particle size of soil is measured, a color measurement value related to a color of the soil is measured, and corrosion of a steel material buried in the soil is estimated from the particle size and the color measurement value. In the measurement of the color measurement value, a color value is measured as the color measurement value. In the corrosion estimation, a corrosion rate is obtained from the measured particle size, a corrosion rate magnification is obtained from the measured color measurement value, a corrected corrosion rate is obtained by multiplying the corrosion rate by the corrosion rate magnification, and the corrosion of the steel material is estimated according to the obtained corrected corrosion rate.
