摘要
A method of measuring a roughness coefficient of a joint surface using an acoustic scan image is provided to accurately and quantitatively calculate the roughness coefficient of the joint surface without using a bore core. A method of measuring a roughness coefficient of a joint surface(11) using an acoustic scan image includes the steps of: obtaining acoustic scan data on the inner surface of a bore hole(30) by irradiating acoustic beam on the inner surface of the bore hole; extracting a roughness curve representing roughness of the joint surface in the bore hole based on the obtained acoustic scan data; calculating a roughness value of the joint surface on the roughness curve; and calculating the roughness coefficient of the joint surface by using correlation with the roughness value.
