Abstract Shale formations as major unconventional energy resources are crucial in satisfying the global needs of future. Via nanoindentation method and upscale method, macromechanical parameters shale, such hardness, elastic modulus, obtained. The conventional Mori–Tanaka only divides data into three mineral classes fails to fully incorporate micromechanical properties reflect macroscale samples. research measures shale via performs cluster analysis measurements. results then combined with...
The yield criterion of rock is significant for the identification whole failure process and stability analysis engineering. Studies criteria from energy aspects are critical but rare. This paper investigated using strain a modified compounded mobilized planes (CMP) model. strength were formulated with different combinations stress variables. Based on conventional triaxial true tests, evolution laws mechanical parameters, including elastic parameters parameter, quantitatively determined....
For rock support in burst-prone ground, the wall-rock velocity adjacent to surface of underground openings is a vital design parameter, and depends on seismic source mechanism inducing rockburst damage. In this study, estimate evoked only by slab buckling (an important mechanism), comprehensive assessment method proposed, using an excellent column model with small eccentricity, which relies novel compressive or tensile failure criterion slab. The true-triaxial loading–unloading tests case...
Fault activation has been the focus of research community for years. However, studies fault remain immature, such as mode and its major factors under constant normal stiffness (CNS) conditions associated with large thickness surrounding rock mass. In this study, friction experiments were conducted to understand modes CNS conditions. Two parameters, i.e. initial stress loading rate, considered calibrated in tests. To reveal response mechanism activation, local strains near plane recorded,...
Numerous deep underground projects have been designed and constructed in China, which are beyond the current specifications terms of scale construction difficulty. The severe failure problems induced by high situ stress, such as rockburst, spalling, damage surrounding rocks, time-dependent damage, were observed during these projects. To address problems, dynamic design method for hard rock tunnels is proposed based on disintegration process rocks using associated control theories...
Cryptocrystalline basalt is one of the two major types rocks exposed in super large-scale underground powerhouse Baihetan hydropower station China. The rock this type shows various site-specific mechanical responses (e.g. fragmentation, fracturing, and relaxation) during excavation. Using conventional triaxial testing facility MTS 815.03, we obtained stress–strain curves, macroscopic failure characteristics, strength characteristics cryptocrystalline basalt. On basis, evolution crack...
