摘　　要：用基于X射线的CT无损检测技术进行岩石损伤检测是岩石损伤力学的重要研究方向之一．首先 介绍X射线CT设备的发展状况、检测原理和技术指标,回顾了CT技术在岩石损伤检测中的应用进展,其 次给出了现有的CT分析方法,提出了统计频率分析法;然后评价了各种基于CT均值的损伤变量;最后指出 岩石CT技术目前存在的问题,并预测了未来的发展方向．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.
