摘要
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。
CT identification technique is applied to study the damage propagation. The in-time CT scanning is used to study the process of damage propagation of rock. It is observed that the quantity, distribution regulation of CT value and its changes are related to the damage propagation of rock. The quantitative relation among stresses, strains and damage propagation is discussed. So the foundation for establishing the constitutive relation of damage propagation of rock is provided.
