岩石是由多种矿物颗粒、孔隙和胶结物组成的复合体,由于地质构造或人为的影响,岩石材料或多或少存在着随机分布的大小不一、形状各异的微观孔隙和裂纹,即岩石存在着损伤的问题。基于这一问题,从岩石的损伤检测这一主题出发,指出岩石损伤检测技术的重要性,并对岩石损伤检测技术中的CT技术、声发射技术本身及其检测原理和检测方法进行了详细介绍。这既在理论上为岩石的损伤检测提供依据,又对揭示岩石损伤扩展和破坏的本质特性具有十分重要的意义。
Rock is composed of a variety of mineral particles, pores and cements composed of complex, due to the geological structure or human influence, there are more or less rock materials randomly distributed in different sizes and shapes of micro-pores and cracks, that is There is a problem with rock damage. Based on this problem, the paper points out the importance of rock damage detection technology based on the subject of rock damage detection, and introduces CT technology, AE technology itself and its detection principle and detection method in rock damage detection technology . This not only provides a theoretical basis for the detection of rock damage, but also is of great significance for revealing the essential characteristics of rock damage expansion and destruction.
