Abstract: The application of X-ray CT technology to rock damage measurement becomes an important part of rock damage mechanics. In this paper, first, the measurement principle, technical specifications and development of the CT machine are described. Secondly, the application of CT technology to rock damage measurement are reviewed. Thirdly, the existing methods of CT analysis, including the statistical frequency method put forward by the author, are discussed. Fourthly, all kinds of damage variables based on mean CT values are analyzed. Finally, the existing problems and future development are pointed out.
