摘要：
The real-in time computerized tomography (CT) test of the meso-damage propagation law of the whole rock failure process has been completed using the newest specified triaxial loading equipment corresponding to the CT machine. Through the CT scanning, the clear CT images which include the microholes (microcracks) compressed→growth→bifurcation→development→crack fracture →the rock sample failure→unloading in the different stress states were obtained. The CT values, CT images and other data have been analysed. The initial damage effect coefficient has been loaded, and a new damage variable based on CT value defined. The initial rock damage propagation law is given here.
