| Abstract: | Using a specified loading equipment corresponding to the CT machine, a contrastive study of meso|damage failure mechanism of sandstone under successive loading and unloading confine pressure condition is accomplished by means of CT real|time testing. It is demonstrated that in the process of unloading, failure of rock is paroxysmal. |
