摘要 | In this paper, we have investigated the quantitative relationship between the axial strain threshold at the volumetric strain reversal point (epsilon (1cd)) and the strain threshold at the peak stress (epsilon (1ucs)) during the uniaxial compression tests. We found that normalized values of epsilon (1ucs)/epsilon (1cd) for different rock types are typically similar to 1.34(+/- 0.24). This is especially true for igneous and metamorphic rocks, or low-porosity sedimentary rocks. To verify this finding, we investigated seven granitic gneiss samples using the uniaxial compression test. Our results were consistent with the above statistics. We inferred that epsilon (1ucs)/epsilon (1cd) may be an intrinsic property of low-porosity rocks, and may be a potential indicator for predicting failure strains in laboratory-scale rock samples. |
