将CT识别技术用于岩石损伤扩展研究，对岩石损伤扩展过程进行即时CT扫描。发现CT数的大小、分布规律及其变化情况与岩石损伤扩展密切相关，揭示了岩石损伤扩展过程中CT数与应力、应变间的定量关系，为建立岩石损伤扩展本构关系奠定了基础。
The CT identification technique was applied to the study of rock damage propagation, and the CT damage scanning was performed on the CT scan. It is found that the size, distribution and variation of the CT number are closely related to the rock damage development, revealing the quantitative relationship between CT number, stress and strain in the process of rock damage propagation, and laying the foundation for establishing the constitutive relationship of rock damage propagation.
