The existing constitutive models of rock with strain softening cannot successfully reflect the damage-induced anisotropy and nonlinearity post-peak failure behavior under progressive loading. In order to better nonlinear stress-strain rock, especially for behavior, expected stiffness degradation large deformation, a modified model considering dilatation at deformation was proposed in this study. This study analyzes discusses various attenuation parameters plastic using FLAC3D software....
Deep geothermal energy is a renewable and environmentally friendly resource, the hot dry rock in reservoir subjected to thermal cycling treatment. Thermal treatment can cause stresses matrix result cracking, which significantly influence physical mechanical properties of rock. To investigate on microcrack propagation behavior granite rock, series tests were performed nontreated treated samples. The testing results show that mass, density, P-wave velocity decrease with heating temperature...
Characterization of the mechanical properties cracked rock masses is essential for ensuring long-term stability engineering environment. This paper aimed at studying relationship between strength characteristics specimen and angle precrack, as well interaction cracks under uniaxial compression. To this end, two sandstone specimens, distinguished with a single three precracks, were built using PFC software. For former case, both peak elastic modulus increase to value crack <math...
Numerical simulation is very useful for understanding the hydraulic fracture (HF) re-orientation mechanism from artificial weaknesses. In this paper, UDEC T-W (Trigon–Weibull distribution) modeling method adopted to simulate fracturing process in heterogeneous rocks. First, reliability of validated against previous laboratory experiments and numerical simulations. Then effects fluid rate, viscosity, perforation angle natural (NF) on HF rocks are studied independently. The results show that...
Microwave pretreatment could be an invaluable method to improve the efficiency of rock breakage in excavation and comminution operations. To investigate influence microwave irradiation on thermal response mechanical behavior compact rocks, a series physical experiments were conducted nontreated treated basalts. The mineral compositions basalts obtained by X-ray diffraction (XRD) test. Scanning electron microscope (SEM) images geological sketch utilized analyze propagation pattern microcracks...
