Description
A new stochastic boundary element method for analyzing the corrosion of underground structure was developed. In case of analyzing the corrosion of underground structure buried in soil which electric conductivity and polarization characteristics are changing along time, it Is necessary to consider about the stochastic character of these unstable condition (conductivity and polarization characteristics) . The non-linear relationship between unknown variables and these unstable condition was linearized by Taylor series and, the mean and covariance of unknown variables are estimated. In order to demonstrate the effectiveness of the method, the simulation was performed and the result was compared with conventional Monte Carlo method and the field experimental result. A computer simulation of the identification is performed at first with a measured potential by using the Kalman filter which stochastic model was considered with the proposed method.
