density damage increment field 密度损伤增量场
Rock density damage increment with ct can be obtained by subtracting ct number of the undisturbed rock samples from that of the loaded rock samples.
通过对岩石试样在加载前后测得的CT数作差值运算，可获得岩石试样在不同应力阶段的CT密度损伤增量。
It is tested that the density damage increment not only reflects the damage degree of rock but also describes the meso-damage process of rock. The further discussion shows...
进一步讨论表明，岩石密度损伤增量场能圆满地刻画岩石细观损伤状态和岩石细观损伤过程。
