摘要

在国内外首次利用CT专用岩石三轴试验加载设备，完成了单一裂纹岩石卸围压应力作用下损伤破坏全过程CT实时监测试验，得到了非常清晰的节理岩石卸围压破坏全过程中从裂纹发展、贯通到破坏等各个阶段的CT图像。结果表明，节理岩石的卸载破坏具有突发性。

Abstract

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
