PROBLEM TO BE SOLVED: To provide a maintenance method selection method of a concrete surface and a device thereof capable of specifying an appropriate maintenance site from the distribution of chloride ion concentration detected by spectral analysis.SOLUTION: Each grade of the deterioration state of a concrete surface S is associated with chloride ion concentration, and concentration degree sections G to A having a chloride ion concentration value are set up for each grade, and the repairing methods 4 to 1 recommended for respective concentration sections G to A are determined. After that, the concrete surface to be repaired is divided for each mesh so as to measure chloride ion concentration, and a contour map 31 based on the concentration sections G to A is prepared from chloride ion concentration for each mesh and sectioned by a division line L, and the repairing method of the concrete surface to be repaired is divided so that the aggregation of respective concentration sections G to A described in the contour map 31 includes an aggregation Gof the concentration section G in order from the high concentration section G. |
