%X By using integrally the sensitivity features of acoustic emission location technology and the computerized tomography(CT) technology,the fine test on progressive fracturing process of jointed rock under uniaxial compression is realized. By analyzing the positions of acoustic emission events,the CT slides and the change of CT number,the cracking propagation process is achieved. At the beginning of loading,although the whole jointed rock sample shows of crack compaction,the initial crack extension can be localized in the partial area. With the load increasing,both sides of the cracks extend gradually,and they will be destroyed progressively until to form a fracture plane finally. The results can lay the foundation for exploring micro-damage mechanism and the crack expansion discipline of rock,and it will also promote the development of visualization technology for rock mechanics test.
