Abstract This work presents particle-based numerical simulations on coal pillars in a mine based underground water reservoir (CMUWR). We aim to replicate the stress–strain characteristics and present acoustic emission behavior of under complex dynamic stress paths. The study reveals failure exposed monotonic/cyclic shear load constant/cyclic normal loads. Based evolution stress-time-dependent bond diameter implemented particle model, different damage paths are established for dry...
Abstract The frictional rupture mechanisms of rock discontinuities considering the dynamic load disturbance still remain unclear. This paper investigates transitional behaviors slip events happened on a planar granite fracture under cyclic normal stress with different oscillation amplitudes. experimental results show that activations fast slips always correlate unloading stress. Besides, intensive can weaken shear strength which is recoverable when return to constant. patterns are quantified...
Abstract Slide-hold-slide (SHS) test is an essential experimental approach for studying the frictional stability of faults. The origin SHS framework was established based on a consistent constant normal stress, which cannot truly reflect stress disturbance around fault zones. In this paper, we conducted series ‘dynamic tests’, includes oscillations in relaxation stage with different oscillation amplitudes and frequencies synthetic quartz gouge using double direct shear assembly. results...
Infilled joints or faults are often subjected to long-term stable shear forces, and nature surface processes of normal unloading can change the frictional balance. Therefore, it is essential study sliding behavior such granular materials under conditions, since they usually filling matter. We conducted two groups direct tests considering variables: rate magnitude constant force. Dry sands may slide discontinuously during unloading, slip velocity does not increase uniformly with time. Due...
Slip characteristics of tectonic faults are highly correlated with earthquake risks. However, the stress conditions in-situ not static, because tides and seismic waves produce dynamic disturbances. The effect fluids also needs to be considered. fault slip evolution considering both, perturbation fluid pressure is poorly investigated in laboratory.We performed direct shear tests on saw-cut granite joints using a box device external syringe pump. lower part specimen was driven by constant load...
Abstract During geothermal resource exploitation, the potential deterioration of mechanical properties in high‐temperature granite subjected to cooling poses a significant safety concern. To address this, present study investigates coupled thermo‐mechanical behavior during heating and through combination laboratory tests finite difference method analysis. Initial investigations involve X‐ray diffraction, thermal expansion test, thermogravimetric analysis, uniaxial compression test. Results...
The mastery of the spatio-temporal variations in ecological environment quality Taihang Mountain area and its influencing factors are significant importance for coordinated development protection socio-economic Region. Based on Google Earth Engine （GEE） remote sensing index （RSEI）, distribution characteristics from 2001 to 2021 were studied, a structural equation model was used quantify direct indirect impacts natural anthropogenic activities this area. results indicated that study mainly at...
The dynamic frictional behaviors of natural discontinuities (joints, fractures, faults) play an important role in geohazards assessment; however, the mechanisms fault weakening/strengthening are still unclear. In this paper, a shear box was used to perform direct tests on saw-cut (planar) and (rough) granite with different normal load oscillation amplitudes. Based recorded forces displacements, forces, apparent friction coefficients displacements found change periodically oscillated loads...
Abstract This work presents experimental tests based on coal collected from a mine underground water reservoir (CMUWR). The mechanical responses of dry and water-soaked samples under the complex normal shear stresses multi-amplitude variable frequency is investigated. results reveal effects stress path, soaking deformation, energy dissipation, secant modulus failure surface roughness. show that when are applied simultaneously, there significant competitive relationship between them.
