It is the first time that using the newest specified loading equipment corresponding to the CT machine
the real-time computerized tomography testing of meso-damage propagation law of jointed rock sample with single crack under unloading confining pressure has been accomplished in rock mechanics fileld. Through CT scanning
the clear CT images are obtained to include the whole process of rock failure on unloading confining pressure from the crack development
penetration and fracture failure in the different stress states. It is clear that it is easy for failure phenomenon to happen suddenly in the process of unloading condition of jointed rock
