Numerous fissures, joints and faults exist widely in natural rock masses which played an important role in the geotechnical engineering. Experimental and numerical methods are very important to the researches of jointed rock mass. The improvement measures of Discontinuous Deformation Analysis numerical method make it more suitable for the failure process of jointed rock mass. A rock specimen was tested under compression by experimental method and numerical method. The numerical test of failure process that improved Discontinuous Deformation Analysis method matches well with the experiment of rock specimen. The process proved that the improved Discontinuous Deformation Analysis method could effectively simulate the failure process of jointed rock mass. Additionally, detailed initiation and propagation process of secondary cracks were shown in the research. The initiation and propagation of secondary wing cracks were significant behaviors during the failure process of jointed rock mass. Detailed crack extending process had been discussed deeply and it could be useful for the theoretical research.
