NEUTRALIZATION DEPTH PREDICTION DEVICE OF CONCRETE STRUCTURE AND PROGRAM FOR INSTRUCTING COMPUTER TO CALCULATE NEUTRALIZATION DEPTH

摘要

PROBLEM TO BE SOLVED: To precisely predict a temporal progress in neutralization depth while taking an uncertain error of a mathematical formula model into consideration.;SOLUTION: Process steps that a neutralization depth prediction device 100 executes include a step (S1) of setting a statistical mathematical formula model for predicting a neutralization depth of concrete used for a structure, a step (S2) of loading data (structure data) on the neutralization depth of the concrete obtained through inspection, a step (S3) of setting a prior distribution and a likelihood function of parameters to be estimated (a neutralization speed coefficient, exponentiation of the number of elapsed years, and variation), a step (S4) of numerically generating a post distribution by an MCMC (Markov chain Monte Carlo) method, and a step (S5) of estimating the parameters based on the post distribution.;COPYRIGHT: (C)2012,JPO&INPIT
