A method for analyzing the strength of an aged concrete and a shotcrete is provided to measure the aged degree and the change in the strength of a concrete structure. A method for analyzing the strength of an aged concrete and a shotcrete includes the steps of measuring a load, a bit rotation force, the size of a core, the size of a drill, and a depth under a predetermined condition during a coring or drilling operation(20), sorting and classifying the measured materials for operation conditions and converts the measured materials into a data base(30), reviewing the input measured materials by utilizing the materials of the data base(40), improving the reliability of a compression strength assumption equation by utilizing the materials of the data base(60), and assuming the compression strength by using an assumption equation from the constructed data base. |
