Abstract: Using the special purpose loading equipment made by authors corresponding to CT machine ,the computerized tomography (CT) real-time testing of specimen’s failure with single fracture and hydraulic pressure under uniaxial compression has been made. The whole procession of specimen being compressed, new damage coming up and the failure process of hydraulic fracture of rock are simulated .At different axial pressure ,clear CT images and CT values of different parts are obtained .With studying the data of test , the threshold value of damage and damage propagation rate are defined; and some discussion of hydraulic pressure’s effect is made. The damage and fracture propagation law of jointed rock has been obtained from meso-scale and three dimensions.

Key words: CT real-time test, jointed rock with hydraulic pressure, three dimensions damage propagation law
