英文摘要Sandstone properties can be greatly influenced by water, and many scholars have investigated the interaction between sandstone and water, but paid less attention to the assessment of crack development, fragment features, and damage evolution, which are important factors for evaluation of hydraulic fracturing effect. In this study, uniaxial compression tests were conducted on sandstone specimens in dried, natural, and saturated state, respectively. The generated fragments were collected, and acoustic emission signals were recorded continuously. The grain size distribution and shape description as well as fractal dimension of fragments were all analyzed. Moreover, AE parameter evolution of RA (the ratio of rise time to amplitude) versus AF (average frequency) was obtained and AE damage analysis was carried out. Compared to saturated specimens, dried and natural specimens generated a larger amount of fragments in medium, fine, and micro-grain groups with relatively larger fractal dimension. The average release of cumulative AE energy of dried and natural specimens is much greater than those of saturated specimens. The distributions of RA versus AF imply that water saturation increases tensile fracture whereas decreases shear fracture, which are consistent with the macroscopic failure modes. Compared to saturated and natural specimens, dried specimens which generate more macro-flaws have relatively lower damage correction factor eta and higher damage variable D-0. The obtained results can be used as the scientific bases to study sandstone weakening mechanism under water influence.
