摘要
利用已研制成功的CT (ComputerizedTomography)机专用三轴加载实验设备 ,完成了三轴压缩荷载作用下岩石损伤演化CT实时细观实验 .确定了应力损伤阈值 ,对CT实验结果进行了定量分析 .从工程应用出发 ,给出了峰前分段岩石损伤演化方程及本构关系 .
Using the specified loading equipment corresponding to the CT machine developed by the authors,the computerized tomography (CT) real in time testing of rock meso damage propagation law under the triaxial compression have been completed. The stress threshold value of damage is determined.The quantitative analysis of testing results has been completed. And based on the aim of the application of engineering,the pre peak rock 3 parts damage evolution equation and constitutive model are given. The theory results is identical to the testing results.
